Question

A truck of mass 100 kg starts at rest and moves in a straight road with constant acceleration 5 m/s2 .What is the momentum after 5 sec?

Answer 1

Answer:

2500kgm/s

Explanation:

V=U+at

V=0+5m/s²*5/s

V=25m/s

So,

P(momentum)=mv(mass*velocity)

P=100kg*25m/s

P=2500kgm/s.Ans

Answer 2

Explanation:

answer is 25 , 000

v = u + at

v = 5 × 5

v = 25

p = mv

p = 100 × 25

p = 25000 kgm/s
