A stunt performer swings on a 33.0 m long cable initially inclined at an angle of 31.0° with the vertical. (Assume the cable has negligible mass.)
a. What is the stunt performer's speed (in m/s) at the bottom of the swing if she starts from rest?
b. What is the stunt performer's speed (in m/s) at the bottom of the swing if instead she pushes off with a speed of 6.00 m/s?
A block is placed on a frictionless ramp at a height of h = 1.35 m above the ground. The ramp forms an angle of 0₁ = 43.3°
with the horizontal. Starting from rest, the block slides down the ramp. At the bottom of the ramp, the block slides onto a
frictionless horizontal track without slowing down. Use g = 9.81 m/s² for the acceleration due to gravity.
