Question

calcuate the kinetic energy of bullet mass of 100g moving with a velocity of 300 m /s

Answer 1

mass of bullet =100g

100/1000=1/10

velocity of bullet =300m/s

                               

kinetic energy=1/2mvsquare

1/2*1/10*300*300=4500joule

Answer 2

Hlooo mate..

here is yur answer.....

K.E. = (m v² /2)
m=100g=0.1kg
v=300m²

so, K.E.=0.1×300×300/2 =4500 joule ans.........

I HOPE IT IS HELPFUL TO YOU.......✌✌✴✌✌
