Question 15

A constant resultant force F F\,F accelerates a block of mass m m\,m from rest along a frictionless horizontal floor to a speed v v\,v over a distance sss, giving it kinetic energy EkE_kEk​. Which pair of relationships for this situation is correct?

A

Ek=12mv2E_k = \frac{1}{2}mv^2Ek​=21​mv2 and Fs=EkFs = E_kFs=Ek​

B

Ek=mv2E_k = mv^2Ek​=mv2 and Fs=EkFs = E_kFs=Ek​

C

Ek=12mv2E_k = \frac{1}{2}mv^2Ek​=21​mv2 and F=EksF = E_k sF=Ek​s

D

Ek=mv2E_k = mv^2Ek​=mv2 and F=EksF = E_k sF=Ek​s
