Question

The speed of a car weighing 1500 kg increases
from 40 m/s to 50 m/s. Calculate the change in its
momentum​

Answer 1

Answer:

the change in momentum = 15*10^3 kgm/s

Explanation:

p=mv

(dp) = m (dv)

dp = 1500 (50-40)

dp = 1500 (10)

dp = 15 * 10^3

hence solved

Answer 2

Answer:

15000 kg m/s

Explanation:

Given : m = 1500 kg

u = 40 m / s

v = 50 m/s

Change in momentum = m× (50-40)

= 1500 × (50 - 40)

= 1500 × 10

= 15000 kg m/s

Therefore, the rate of change of momentum of a car is 15000 kg m/s
