Gaseous helium is in thermal equilibrium with liquid helium at 6.4 k. the mass of a helium atom is 6.65 × 10−27 kg and boltzmann’s constant is 1.38066 × 10−23 j/k. determine the most probable speed of a helium atom. answer in units of m/s.

A10.0 kg cart and a 15kg cart are locked together with a compressed spring between them. they are then released so that the spring pushes the two carts apart. the 10.0 kg cart is moving at 4.5 m/s afterward. how fast is the 15kg cart moving? 3.0 m/s 2.0 m/s 4.5 m/s 5.0 m/s
