Question

A bullet of mass 10g is fired with a velocity of 80 m/s.what is the kinetic energy.

Answer 1

kinetic energy is the energy a body posses while in motion which is given by 1/2mv²

just put the values and you will get that

Answer 2

Hey there!

Answer:

K.E = 32 joules

Explanation:

Given,

Mass = 10 g = 0.01 kg

Velocity (v) = 80 m/s

K.E = ?

We know,

K.E = 1/2 * mv²

= 1/2 * (0.01) * 80 *80

= 32 J
