## How many seconds does it take the ball to reach the ground apex?

6 secondsThe ball takes 6 seconds to reach the ground..

## What is work formula?

We can calculate work by multiplying the force by the movement of the object. W = F × d. Unit. The SI unit of work is the joule (J)

## How can I calculate weight?

Weight is a measure of the force of gravity pulling down on an object. It depends on the object’s mass and the acceleration due to gravity, which is 9.8 m/s2 on Earth. The formula for calculating weight is F = m × 9.8 m/s2, where F is the object’s weight in Newtons (N) and m is the object’s mass in kilograms.

## What formula calculates force?

It is summarized by the equation: Force (N) = mass (kg) × acceleration (m/s²). Thus, an object of constant mass accelerates in proportion to the force applied. If the same force is applied to two objects of differ- ent mass, the heavier object has less acceleration than the lighter object (Figure 1).

## How long will it take the ball to reach its maximum height?

1 Expert Answer So the ball reaches its maximum height after 3 seconds.

## How do you calculate the force of gravity?

Understand Newton’s Second Law of Motion, F = ma.This law can be summed up with the equation F = ma, where F is the force, m is the mass of the object, and a is acceleration.Using this law, we can calculate the force of gravity of any object on the surface of the earth, using the known acceleration due to gravity.

## How do you calculate the force of an angle?

Subtract the angle between the force and the resultant vector you want to calculate from 90. If, for instance, the force acts at a 30-degree angle from the object’s direction of motion then 90 – 30 = 60.

## How do you calculate the force exerted on the ground?

As its initial velocity is 0, with a little bit of calculations, it can be found that v=√2gh. So, the linear momentum(p) of the body on striking the ground =Mv=M√2gh.

## How do you calculate the force of a falling object?

An object that is falling through the atmosphere is subjected to two external forces. The first force is the gravitational force, expressed as the weight of the object, and the second force is the aerodynamic drag of the object. … W = m * g. … D = Cd * .5 * r * V^2 * A. … F = m * a. … a = F / m. … F = W – D. … a = (W – D) / m.

## How long until the ball hits the ground?

three secondsIt takes three seconds for the ball to hit the ground. Note: On Earth, it would take a little over nine seconds for the ball to fall back to the ground.

## What will be the height of the ball after 2 seconds?

12.4 meters, this means that the height of the ball after 2 seconds is 12.4 meters. The -4.9t^2 is the force of gravity pulling it down and the 15t is the ball being thrown keeping it up.

## What is the formula for calculating speed?

The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time.

## What is the normal force equal to?

mgNormal force is equal to mg only when the object is placed horizontally, and the force is acting in the direction of the gravitational field. Here you will see that the weight of the body is passing through the Centre of gravity and acting in direction of the centre of the earth.

## Is the force that slows down a kicked ball?

The moment the ball leaves the foot, it stops accelerating, and from this point forward only two forces are exerted upon it: the friction with the air, which slows the ball’s motion, and gravity, which pulls it down. As the ball moves, it slows and falls down.

## How do you calculate when an object hits the ground?

Choose how long the object is falling. In this example, we will use the time of 8 seconds. Calculate the final free fall speed (just before hitting the ground) with the formula v = v₀ + gt = 0 + 9.80665 * 8 = 78.45 m/s . Find the free fall distance using the equation s = (1/2)gt² = 0.5 * 9.80665 * 8² = 313.8 m .

## How long will it take for an object to hit the ground?

So, if I drop an object from rest at 6750 meters up and ignore everything but gravity, it would take about 37.12 seconds to reach the ground.

## How far do you fall in 2 seconds?

The first equation shows that, after one second, an object will have fallen a distance of 1/2 × 9.8 × 12 = 4.9 m. After two seconds it will have fallen 1/2 × 9.8 × 22 = 19.6 m; and so on.

## How do you calculate time it takes for an object to fall?

Measure the distance the object will fall in feet with a ruler or measuring tape. Divide the falling distance by 16. For example, if the object will fall 128 feet, divide 128 by 16 to get 8. Calculate the square root of the Step 2 result to find the time it takes the object to fall in seconds.

## How many seconds will it take the object to reach the ground second s?

Thus, it will take the object 10 seconds to reach the ground.

## What is the force of an object falling?

An object that is falling through a vacuum is subjected to only one external force, the gravitational force, expressed as the weight of the object. … The motion of a free falling object can be described by Newton’s second law of motion, force (F) = mass (m) times acceleration (a).
