Two objects are moving at equal speed along a level, frictionless surface. the second object has twice the mass of the first object. they both slide up the same frictionless inclined plane. which object rises to a greater height?

An isolated box with volume V is initially split into two halves by a partition. One side has gas at temperature T with pressure P and number of molecules N, and the other side has nothing (it is a void).

A 0.05 kg weight is used to accelerate a cart. At t=1 second, the 0.5 kg cart is at x=0.5 m, at rest. At t=2.5 seconds, the cart is at 1.5 m, traveling at 1.3 ± 0.3 m/s.
