The velocity of a 2 kg object initially moving at ( – 2i +3j -5k) m/s changes to ( i +3j+4k) m/s after 3 s. The magnitude of the force acting on the body is (a) 2√3 N (b) 2√10 N (c) 6√3 N (d) 12√3 N

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.

What is the angular momentum of the bar about the axle?
