Question

Step 4: Solve the equation.
KE = 27.5 kg x 4 m²/s2
=

Answer 1

Kinetic energy is 1/2m*v^2
They already halved the mass for you and they already squared the velocity for you. I’m unsure why you’re even asking this question. It’s simple multiplication at this point.
(27.5kg)*(4m^2/s^2) = 110 Jules
