rate of 3000 rpm.8. A ski lift has a one-way length of 1 km and a vertical rise of 200 m. The chairs are spaced 20m apart, and each chair can seat three people. The lift is operating at a steady speed of 10km/h. Neglecting friction and air drag and assuming that the average mass of each loadedchair is 250 kg, determines the power required to operate this ski lift. Also estimate thepower required to accelerate this ski lift in 5 s to its operating speed when it is first turnedon.

Answered: 8. A ski lift has a one-way length of 1…

A small 0.18 kg metal ball is tied to a very light (essentially massless) string that is 0.60 m long. The string is attached to the ceiling so as to form a pendulum. The pendulum is set into motion by releasing it from rest at an angle of 50 degrees with the vertical. I solved that the speed of the ball when it reaches the bottom of the arc is 2.0 m/s and the tension of the string is 3.0 N What is the centripetal acceleration of the ball at this point?
