How fast is the wagon going

  • #1
A 40.0 kg wagon is towed up a hill inclined at 18.0° with respect to the horizontal. The tow rope is parallel to the incline and has a tension of 140 N. Assume that the wagon starts from rest at the bottom of the hill, and neglect friction. How fast is the wagon going after moving 77 m up the hill?


so all i need is the accel to do this one, how do you find it using a box moving up a incline i only know going down.

for box going down show your work.

Hint
Tension is the driving force and component of gravity is opposing.

The only difference between going down a slope and going up is the direction!

Of course the acceleration due to gravity is always down so it's really the difference between adding and subtracting.
