Question

An object of mass 100 kg is accelerate uniformly from me velocity of 4m / s to 8ms into 2seconds . calculate the initial and final momentum of the objects .
O 400 kgm/s,800 kgm./s
O 100 kgm/s,400 kgm./s
O 200 kgm/s,400 kgm./s
O 400 kgm/s, 400 kgm./s​

Answer 1

Answer:

Explanation:

we know that momentum is a product of mass and velocity. therefore, initial momentum will be : 100*4= 400m/s and final momentum will be :               8*100 = 800 m/s.
