Question

a loading truck with a mass of 38000 kg is travelling at 1.20m/s. what will be velocity of a 1200 kg car if it has same momentum

Answer 1

Answer:

68 m/s

Explanation:

Put the formula of momentum

P=mv

For truck momentum will be p=(38000×2.20)kg m/s

P=83600kg m/s

Since car is moving with the same momentum

P'=p=m'v'

83600=1200 x v

V=68 m/s

The level of the car will be 68 m/s
