A child rolls a 0.600-kg basketball up a long ramp. The basketball can be considered a thin-walled, hollow sphere. When the child releases the basketball at the bottom of the ramp, it has a speed of 8.0 m/s. When the ball returns to her after rolling up the ramp and then rolling back down, it has a speed of 4.0 m/s. Assume that the work done by friction on the basketball is the same when the ball moves up or down the ramp and that the basketball rolls without slipping. Find the maximum vertical height increase of the ball as it rolls up the ramp.
The simply supported beam in Figure Q2a is in equilibrium and the reaction force RA is 9.92 N. Determine the reaction force at RB and calculate the distance x m. *Assume that the weight of the beam is zero.
In the figure, a 58 kg sphere is supported on a frictionless plane inclined at angle 0 = 42° from the horizontal. Angle p is 23°. Calculate the tension in the cable.
