Question

the kintic energy of body of mass 50 grams moving with a velocity of 5 m/sec is .​

Answer 1

Answer:

Kinetic  Energy = $\bold\huge{\frac{1}{2}}$ × $\bold\huge{\frac{50}{1000}}$ × 5²

                       

                          = 0.625 Joules

Answer 2

Answer:

mass=50gm =50/1000 kg

velocity=5m/sec

K.E=1/2mv²

= 1/2x50/1000x5x5

=0.625 joule
