Question

Four people a, b, c and d of masses 7,9,5 and 13 ( in kg) respectively are moving with their respective velocities in the ratio 4:3:5:2. Who will have the highest momentum. option a,b,c,d.

Answer 1

Answer:

Momentum of a is the greatest.

Explanation:

Let their velocities be a,b,c and d be 4x, 3x, 5x,2x respectively

Momentum is given by mass× velocity

                              Momentum of a  = 7× 4x= 28x

 Momentum of b  = 9× 3x= 27x

 Momentum of c  = 5× 5x= 25x

 Momentum of d  = 13× 2x= 26x

Momentum of a is the greatest.
