3. A 20 kg monkey is hanging from two branches. Each of its arm makes a 45° angle with
the x-axis. The monkey is not moving and it is not about to move. Calculate the tensions
in the monkey's arms. (139 N)
4. A child holds a sled at rest with a light rope on a frictionless snow-covered hill. The
weight of the sled is 100N. The hill makes an angle of 35.0° relative to the horizontal. (a)
Calculate the magnitude of the force that the child must exert on the rope to hold the
sled (b) Calculate the magnitude of the normal force that the hill exerts on the sled.
