Answer:
initial momentum of the object = 100*5=500 kg.m/s.
final momentum of the object = 100*8=800 kg.m/s.
force= 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.
