M R h A hollow sphere rolling (without slipping) upward from the bottom of the ramp. The initial speed of the center of mass is 1 m/s. It stops at height h above the horizontal. Find h.

Please help showing how to solve this question. According to Canvas, the answer should be 1.367 m/s.

+ Log o A horizontal 869 N merry-go-round of radius 1.63 m is started from rest by a constant horizontal force of 60.3 N applied tangentially co the merry-go-round. Find the kinetic energy of the merry-go- round after 3.7 s. The acceleration of gravity s 9.8 m/s2. Assume the merry-go-round is a solid cylinder. Anşwer in units of J. 015 10,0 points

A ball with an initial velocity of 8.61 m/s rolls up a hill without slipping. (a) Treating the ball as a spherical shell, calculate the vertical height (in m) it reaches. (b) Repeat the calculation (in m) for the same ball if it slides up the hill without rolling. m Additional Materials O Reading

. The forces exerted by the bicep muscle and acting on the elbow when a 12 kg barbell is being curledcan be modeled based on the diagram above. The bicep muscle can be treated as a vertical cable. Themass and length of the forearm are 2 kg and 32 cm, respectively. The center of mass of the forearm is adistance of 14 cm from the point P, while the bicep connects to the forearm at a point 4.5 cm from P.a) Determine the tension in bicep muscle and the force of the humerus acting downward on the elbowat point P. b) Assuming the tension in the bicep muscle continues to be oriented vertically, determinethe tension in the bicep muscle and the force acting at P after the barbell has been raised by an angleof 30 relative to the horizontal.
