Question

two vehicles have their masses in the ratio 1:3 and their kinetic energy in the ration 3:1. The ratio of their velocities are

Answer 1

Answer:

3:1

Step-by-step explanation:

K.E =1/2 mv²

3/1 =1/3 v²/v'²

√9/√1= v/v'

therefore v:v' is 3:1

Answer 2

Answer:

answer of the question is 3:1
