A 25.0 kg sled is pulled (assume frictionless) with a force of 15.0 N at an angle of 20 degrees above the horizontal. (a.) How long will it take to pull the sled 25m? (b.) How fast will the sled be moving after it has been pulled 25.0m?

-V

_{0x}= V

_{0}sinθ

- X = X

_{0}+ V

_{0x}t

- V = V

_{0}+ at

- X = X

_{0}+ V

_{0}t + 0.5at

^{2}

- ∑F

_{x}= ma

_{x}

I was able to solve for the x-acceleration, a

_{x}= 0.56m/s

^{2}but I cannot figure out how to use the given forces and acceleration to solve for the time at 25m. Am I to assume V

_{0}= 0?

This is a practice problem for a quiz that I cannot seem to crack. Please help.
