A 3 kg objects falls from a height of 10 m to the ground. the work done by air resistance is 20 J. What is the kinetic energy of the object as it hits the ground?

Give the potential energy function U = 2×^2-25×: determine the force function for this potential.

Two masses are slideing on a horizon frictionless surface. A 10 kg mass has a velocity of 9 m/s in the x direction and a 20 kg mass has a velocity of 12 m/s in the y direction .the masses collide and stick together, what is he final velocity of the compos...
