Question

Any on pls answer this question

Answer 1

IF MOMENTUM OF A BODY INCREASES BY 50 PERCENT IT'S KINETIC ENERGY WILL INCREASE BY 50 PERCENT

Answer 2

K.E=1/2mv²=(mv)²/2m

P=mv

⇒K.E=P²/2m

K.E1/K.E2=P1²/P2²

P2=(3/2)P1

K.E2/K.E1=9/4

K.E2/K.E1 x100=9/4x100=225

The increase in % is 225-100 = 125%
