An acrobat swings on a 34.0 m long cable initially inclined at an angle of 32.0° with the vertical. (Assume the cable has negligible mass.)

a) What is the acrobat's speed (in m/s) at the bottom of the swing if he starts from rest?

b) What is the acrobat's speed (in m/s) at the bottom of the swing if instead he pushes off with a speed of 5.60 m/s?

Consider an inclined plane at an angle of 40.0°, with a kinetic coefficient of friction of 0.350 and a static coefficient of friction of 0.450. A block with mass of 50.0 kg is on the incline and initially at rest. A force of 535 N, parallel to the incline, pushes the block a distance of 10.0 m up the incline. Do the following: a) Determine the speed of the object at the end of this displacement using Newton’s Laws of...
