What is the momentum of a body at rest if its mass is 30kg?

A body of mass 30kg has a momentum of 150kg m//s.

What is free fall class 9th?

When a body or object falls towards earth due to gravitational force of earth and without any other force acting on it. It is called free. fall.

What is the momentum of a body of mass 10kg if the body is at rest?

The momentum of a body of mass 10 kg is 30 kg m/s.

What is the momentum of a body of mass 10 kg if the body at rest?

Explanation: Answer: Therefore, the momentum of a body of mass kg if the body is at rest is zero.

What is the velocity v of the rock when it hits the ground?

When a rock hits the ground, the velocity is zero.

What is the speed at which a 50 kg object falls?

The 50 kg mass returns to the ground with a speed of 20 m/s, which is exactly the same as the speed of the 25 kg mass. If there was no air resistance or drag, the 25 kg mass and the 50 kg would fall at the same rate of 10 m/s 2. Dropped from the same height, they both hit the ground at the same speed and after the same period of time.

How do you calculate free fall distance from height?

Find the free fall distance using the equation s = (1/2)gt² = 0.5 * 9.80665 * 8² = 313.8 m. If you know the height from which the object is falling, but don’t know the time of fall, you can use this calculator to find it, too!

How fast do you fall when you hit the ground?

Gravity accelerates you at 9.8 meters per second per second. After one second, you’re falling 9.8 m/s. After two seconds, you’re falling 19.6 m/s, and so on. Time to splat: sqrt ( 2 * height / 9.8 )

What is the speed at which you fall with gravity?

Gravity accelerates you at 9.8 meters per second per second. After one second, you’re falling 9.8 m/s. After two seconds, you’re falling 19.6 m/s, and so on. Time to splat: sqrt ( 2 * height / 9.8 ) It’s the square root because you fall faster the longer you fall.
