Question

an object mass100kg is accelarted uniformly from a velocity of 5m/s to 8 m/s in 6 second.calculate the momentum?Hint P=m(v-u)​

Answer 1

Answer:

50 N

Explanation:

mass of the object = 100 kg.

time taken = 6 sec.

initial velocity = 5 m/s.

final velocity = 8 m/s.

initial momentum of the object = 100*5=500 kg.m/s.

final momentum of the object =  100*8=800 kg.m/s.

force required = rate of change of momentum / time taken.

force=(800 - 500) / 6

force=300/6

force= 50 N.
