Homework Statement
Homework Equations
The Attempt at a Solution
I solve question a) by rearranging the F=m*a equation, which makes the acceleration equal to (24N/18kg)=1.30m/s^2. And I find the final speed using equation W=1/2*m*v^2 and rearranging it to solve for v, which gives me a value of v=3.27m/s.
But the part of the question I am having trouble with is when it asks me to find how much power is supplied at the beginning and end of the push. How to find that? I know that average power equals change in work over change in time, but using this formula doesn't seem to lead anywhere. I guess there must be another equation I can't think of?
Anybody has a better attempt?
