Question

a bullet of mass 10 g is fired wirh a velocity of 80 ms -1 .calculate its kinetic energy.

Answer 1

Hey there!

Answer:

32 m/s

Step-by-Step Explanation:

Given,

Mass = m = 10 g = 0.01 kg

Velocity = v = 80 m/s

We know,

K.E = 1/2 mv²

K.E = 1/2 * 0.01 * 80 * 80

K.E = 64 / 2

K.E = 32 m/s

Hope It Helps You!

Answer 2

Answer:

Mass = m = 10 g = 0.01 kg

Velocity = v = 80 m/s

We know,

K.E = 1/2 mv²

K.E = 1/2 * 0.01 * 80 * 80

K.E = 64 / 2

K.E = 32 J
