Question

Momentum update: Just after releasing the block, the momentum of the block is zero. Approximate the average net force during the next time interval by the force you just calculated. At t = 0.07 seconds, what will the new momentum and velocity of the block be?py = __. vy = ___.

Answer 1

Answer:

py = 0.0686m and vy = 0.0686 m/s

Explanation:

by using the first equation of motion under gravity i.e. $v_{y =v_{0y +gt$ we can find vy putting voy=0 and g=9.8 m/s2 and t=0.07 sec.

by using relation p=mv we can calculate relation for momentum
