What would be the average velocity of an object falling 1.25m from the rest?

What would be the average velocity of an object falling 1.25m from the rest, just as it strikes the ground?

On a distant planet, an astronaut drops a wrench. The wrench falls a distance of 1.52m in a time of 0.705s. What is the acceleration due to gravity on this planet?

Two carts of masses m and 3m are at rest on a horizontal frictionless track. A person pushes each cart with the same force F for 5 s. If the kinetic energy of the lighter cart after the push is K = 180J, the kinetic energy of the heavier cart is :

A car in an amusement park travels without friction on a vertical loop of 20 m radius. Calculate from what minimum height h it needs to be released from rest in order to remain on the track at the top of the loop.

A mass oscillate with SHM of amplitude A and period T y = A cos (2πt/T). The kinetic energy of the mass is equal with twice the potential energy of the spring at :

The part of an iceberg that extends above the water for ice density of 0.9g/cm3 and salted water of 1.1 g/cm3 is
