Question

A shot-putter throws a 4.00 kg shot at a speed of 10.0 m/s. What is the kinetic energy of the shot?

A. 40 J
B. 200 J
C. 400 J
D. 800 J

Answer 1

here we have to apply this formula:
\[\Large KE = \frac{1}{2}m{v^2} = \frac{1}{2} \times 4 \times {10^2} = ...Joules\]

Answer 2

200! so 200 J is our solution?

Answer 3

yes! correct!

Answer 4

yay! thanks! onto the next:)

Answer 5

:) ok!
