Question

A] A 40.0 kg wagon is towed upa hill inclined at 17.5° with respectto the horizontal. The tow rope is parallel to the incline and hasa tension of 140 N. Assume that the wagon starts from rest at thebottom of the hill, and neglect friction. How fast is the wagongoing after moving 76 m up the hill?
1 m/s
B] A 3.2 kg bucket of water is raisedfrom a well by a rope. If the upward acceleration of the bucket is2.4 m/s2, find the forceexerted by the rope on the bucket.

this is multiple posting. one question is allowed for apost.

   T = m (g + a)
   = 3.2 ( 9.8 + 2.4 )
   =39.04N
