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?​

Answer 1

Heya!!

✒Momentum = mass × velocity.

✴Person A

Momentum = 7 × 4 = 28

✴Person B

Momentum = 9 × 3 = 27

✴Person C

Momentum = 5 × 5 = 25

✴Person D

Momentum = 13 × 2 = 26

Hence, person A has the highest momentum.

Answer 2

As we know p(momentum)=m(mass)×v(velocity)

P=mv

So momentum of A = 7×4

= 28

Momentum of B= 9×3

=27

Momentum of C= 5×5

= 25

Momentum of D = 13 × 2

= 26

Hence B has highest velocity
