Question 141,= 2.5 m sA 4500 kg truck is stuck at the bottom of a ditch. A winchV =0h30°(small motor attached to a cable) cable is attached to a tree at the top of the ditch, and used to extract the truck. The winch puts out a constantof 2.05 kW, the ditch slopes up at 30° from the horizontal, the truck is accelerated from 0.0 to 2.5 m/s during the extraction, and thepowercoefficient of kinetic friction between the truck and the ground is 0.56. How long does it take to drag the truck up to a height of h = 2.65 mabove the bottom of the ditch? Note: ignore any energy needed to rotate the truck. (1446)%3D

Final velocity = 2.5 m/s Initial velocity = 0 m/s Mass m = 4500 kg Power = 2.05 kW

1. A 23.0 kg child is playing on a swing with a length of 2.5 m. If the swing starts from rest and makes an angle of 40.0◦ with the vertical at the top of the swing, a) determine the child’s speed at the bottom of the swing neglecting friction. b) If the swing has a speed of 2.8 m/s at the bottom, determine the work done by friction during the downswing and, bonus) assuming the force of friction is constant, determine the maximum angle the swing attains on the upswing after passing through the bottom. Hint: Use the approximation that cos θ ≈ 1 − 1 2 θ 2 for angles given in radians.
