A mouse-trap car of mass 12 kg is attached to a string of radius 2 meters. 25 poir The car has a rotational speed of.54 radians per second. What is the
tangential velocity of the car? *
O 3.7 m/s
1.08 m/s
24 m/s
O 6 m/s

Asap and show ! a 14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.
