In one of the experiments, the trolley of mass 0,2 kg is on a frictionless horizontal table. The trolley is joined to a hanging masspiece of mass 0,05 kg. The trolley and
the masspiece are joined together with an inelastic string of negligible mass and
runs over a frictionless pulley,

Find the momentum for a 2.6-kg brick parachuting straight downward at a constant speed of 8.4 m/s .

Ablue car pulls away from a red stop-light just after it has turned green with a constant acceleration of 0.5 m/s 2 . a green car arrives at the position of the stop-light 6.5 s after the light had turned green. if t = 0 when the light turns green, at what time does the green car catch the blue car if the green car maintains the slowest constant speed necessary to catch up to the blue car? answer in units of s.
