Answer:
60.18 N
Explanation:
Given that:
The force applied on the sled = 100 N
Suppose, the angle between the sled rope and the ground = 53°
The horizontal force which acts in the horizontal direction can be expressed as:



But if the angle between the sled rope is parallel to the ground. Then, we use an angle on a straight line which is = 180°


= 100 × -1
= -100 N

Answer:
potential energy PE = M g h
KE at bottom = 1/2 M V^2
Regardless of the slope of the slide the change in energy is the same
1/2 V^2 = g h
V = (2 g h)^1/2 = (2 * 9.8 m/s^2 * 10 m)^1/2 = 14 m / s
Perhaps the question says that h = 55 * .1 = 5.5 m
Then V = (2 * 9.8 * 5.5) = 10.4 m/s
