What is the speed of a 5kg mass on reaching the ground when dropped from a 10m high building?

What is the speed of a 5kg mass on reaching the ground when dropped from a 10m high building?

14m/s
14m/s.

What happens to the energy of a ball that is dropped from a 5ft table?

Energy cannot be created or destroyed, but can be transformed. If a ball drops, energy is transferred and transformed, in sound for instance, but the total amount of energy remains the same.

What happens when you drop a ball?

When you drop the ball, it gains ‘kinetic’ energy (the energy of motion) and loses its potential energy. When the two balls are dropped at the same time, they hit each other (collide) just after they hit the ground, and a lot of the kinetic energy in the larger ball is transferred to the smaller ball.

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.

What is the kinetic energy of a ball in joules?

Near the Earth’s surface, we have that v = g t = 9.8 × 5 = 49 meters per second. The kinetic energy of the ball will be K E = 1 2 m v 2 = 0.5 × 2 × 49 2 ≈ 2400 joules. Since energy is force times distance, we get E = F d or 2400 = 120 F.

What is the speed of an object traveling 5m above the ground?

Therefore, it is travelling at 20m/s 5m above the ground neglecting air friction. There are more details here than you need to solve the problem. Also, presumably this is on Earth, were the acceleration from gravity is 9.81 m/s^2.

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)
