A 2 N force acts on a 10-kg mass. If the momentum of the mass changes by 120 kg m/sec...?

Question

Determine the time over which this force acts.

Answer 1

∆p = 120 kg-m/s = (2 N)∆t
∆t = (120 N-s)/(2 N) = 60 s

Answer 2

F=ma yet "a" could be expressed as v/t F=mv/t they supply you rigidity, mass, and time so clean up for v. Assuming that the item starts off from relax, the replace will merely be the linked fee you calculate. Multiply the linked fee you get with the aid of the mass and you will want the momentum.
