a skater has a mass of 78 kg is pushes with a constant force of 137N for a time of 3.3 sec on the ice. the coefficient of friction of the blades against the ice is 0.007.

1. find the skaters acceleration, taking friction into account.

2. how fast is the skater going at the end of the push?

3. how much distance has the skater covered during the push?

what i first did was find acceleration

a=f/m i got 1.74 m/s

^{2}

now what I am stuck on is part 2 and 3...is the Final Velocity and Intial Velocity zero?

someone please help me start off this problem :)
