No friction present means: Ek = Ep
So Ek = mgh = 10 * 9.8 * 2 = 196 J
This is correct, I just did the test. Yes, displacement is 45 meters, elapsed time is three seconds, and the direction is toward the goal.
Answer:
Work = 5941 J
Explanation:
As we know that work done is given by the equation

here we know that

also we have

now from above formula we have
