Question

A bullet of mass 30 g is shot from a gun. It gains a velocity of 320 m/s. Calculate the kinetic energy of the bullet.

Answer 1

Answer:

=1536

Explanation:

kinetic energy= 1/2 mv²

here, m= 30g =30/1000 kg= 0.03 kg

      v= 320m/s

∴K.E. = 1/2(0.03)(320)²

        =1/2 (0.03)(102400)

        =1536
