Question

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 *
1 point
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:

a)400kg.m/s,800kg.m/s

Explanation:

momentum=mass × velocity

so,

initial momentum=100×4=400kg.m/s

final momentum=100×8=800kg.m/s

hope it helps

Answer 2

Answer:

a)400kg.m/s,800kg.m/s

momentum=mass × velocity

so,

initial momentum=100×4=400kg.m/s

final momentum=100×8=800kg.m/s
