Question

A 350 kg motorcycle moves with a velocity of 30 m/s. What is its kinetic energy?
10500 Joules
c. 31500 Joules
b. 157500 Joules
d. 900 Joules

Answer 1

Answer:

C 31500

Explanation:

1/2mv*2=KE

k.e= 350× (30)*2

=350×900

k.e= 31500

Answer 2

It is d because you have to do 300 - 50 then take of the zero for 30.After that do 3x300 and you get 900
