Question

Find the kinetic energy of a bullet if it has a velocity of 700 m/s and a mass of 0.2kg

A) 70J

B) 19,600J

C) 49,000J

D) 196000J

Answer 1

K.E. = 49000 J

Step-by-step explanation:

K.E. = 1/2 m v^2

Where

K.E. = Kinetic Energy

m= mass

v= velocity

Simply replace

K.E. = 1/2 (0.2 kg) (700 m/s)^2

K.E. = 49000 J

Note that the units convert to J here
