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

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.

What is the kinetic energy of an object that falls 10m down?

If the object falls 10m to the ground, then right before it hits, all of its potential energy will have been converted into kinetic energy (plus a tiny bit of air friction energy lost in heat). So the kinetic energy will be 1,962 Joules *minus* some tiny amount (whatever amount of energy was lost heating up the air on the way down).

What is the kinetic energy of 10 kg?

For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s 2.

What happens to the gravitational potential energy when a ball is dropped?

The gravitational potential energy is converted to kinetic energy. Gravitational potential energy at the top = kinetic energy at the bottom A ball of mass 0.4 kg is lifted to a height of 2.5 m. It is then dropped, from rest. The ball returns to the ground with a speed of 7.1 m/s.

How high does a 5 kg stone fall from a cliff?

A stone of mass 5 kg falls from the top of a cliff 50 m high and buries 1 m in sand. Find the average resistance offered by the sand and the time it takes to penetrate.

What happens to potential energy when an object is lifted?

If an object is lifted, work is done against the force of gravity. When work is done energy is transferred to the object and it gains gravitational potential energy. If the object falls from that height, the same amount of work would have to be done by the force of gravity to bring it back to the Earth’s surface.
