A grocery cart with mass of 18 kg is pushed at a constant speed along an aisle by a force F = 12 N. The applied force acts at 20° angle to the horizontal. Find the work done by each of the forces on the cart if the aisle is 15 m long. A 60 kg bungee jumper jumps from a bridge. She is tied to a 12 m long bungee cord and falls a total of 31 m. Calculate the spring constant k of the bungee cord. Determine the maximum acceleration experienced by the jumper. A projectile is fired at an upward angle of 45° from the top of a 265 m high cliff with a speed of 185 m/s. With what speed will it hit the ground? Determine the horizontal and vertical components of its final velocity. Blue Mountain ski area claims that its lifts can move 47,000 people per hour. If the average lift carries people about 200 m (vertically) higher, estimate the maximum total power needed.
