Question

The k. E of an object of mass (m) moving with a velocity of 5ms-1 is 25 joule what will be its k. E when it's velocity is doubled? What will be its k. E
When it's velocity is increased three times? ​

Answer 1

Answer:

when velocity will 2 times then kinetic energy'll 4times and when velocity 3 times than k E will9 times

Explanation:

K.E=1/2×M×V^2

25=1/2×M×25

NOW M=2

WHEN VELOCITY 2TIMES =

KE=1/2×2×2×5^2

KE =100
