Q3 An inclined plane making an angle of 0° with the horizontal has a small smooth pulley at its top. The system is released from rest with B at a height of S (m) above horizontal ground. Given Mass A = 15 kg; mass B=10kg; 0= 30•; S = 15m; coeff. of friction, 4, for mass A and the surface = 0.15. Calculate (i) the acceleration of the particles (ii) the speed with which B reaches the ground

"Spock decides to measure the gravitational acceleration on the surface of hishome planet, Vulcan. He does so by swinging a rock at the end of a massless cord in a vertical circle. In order to complete the full circle, Spock finds that the rock needs a minimum speed of 3.0 m/s at the top of the circle. If the radius of the circle is 1.0 m, what is the gravitational acceleration on the surface of Vulcan?" Im not sure which equation to use?
An online video daredevil is filming a scene where he swings across a river on a vine. The safety crew must use a vine with enough strength so that it doesn't break while swinging. The daredevil's mass is 82.0 kg, the vine is 11.0 m long, and the speed of the daredevil at the bottom of the swing has been determined to be 7.60 m/s. What is the minimum tension force (in N) the vine must be able to support without breaking?

(b) Draw force diagrams for the ball when it is at the bottom of the circle and when it is at the top. (c) If its speed is 5.20 m/s at the top of the circle, what is the tension in the string there? (d) If the string breaks when its tension exceeds 22.5 N, what is the maximum speed the ball can have at the bottom before that happens?
