Question

15.An object of mass 100kg is accelerated uniformly from a velocity of 4 m/s to 8 m/s in 2 seconds. Calculate the initial and final momentum of the object.

a. 400 kgm/s,800 kgm./s

b. 100 kgm/s,400 kgm./s

c. 200 kgm/s,400 kgm./s

d. 400 kgm/s,400 kgm./s

​

Answer 1

Answer:

Momentum=Mass*Velocity

Initial momentum=100*4=400kgm/s

Final momentum=100*8=800kgm/s
