Question

A car of mass 100kg is moving with uniform velocity 5ms"!. After 10 sec, it's change in momentum
a) 5000 kgms
0
c) 50 kgms!
d) 100 kgms!
b) 0 kgms!​

Answer 1

mass, m = 100 kg

Velocity, v = 5 m/s

time, t = 10 sec

Change in momentum in due to the change in velocity. Since velocity is uniform hence change in momentum would be zero.

Δp = m ( v – u )

Δp = 0

( d ) 0 kgms
