1.5m 1.5m 45 The uniform diving platform above has a mass of 300 [kg]. A diver of mass 100 [kg] stands on the right edge of the platform. Suddenly, the support strut gives way (so that the platform and diver start spinning around P. You can assume that the black start suddenly vanished). What is the acceleration of the diver downwards at that point? IT IS NOT 9.8 m/s^2.

A painter of mass 130.0 kg stands on a platform of mass 70.0 kg and pulls on two ropes which hang over pulleys, as shown. He pulls each rope with a force of 100.0 N. Assuming a coordinate system where +y is up, calculate the y-component of the acceleration ay. ay can either be positive or negative depending on the direction of the acceleration.

A nervous diver stands at rest at the end of a 31 kg diving
board as shown in the figure. If the mass of the diver is 135 kg
and the board is 4.7 m long, what is the net torque exerted on the
diving board due to gravity about the fixed end of the board?
Assume the mass of the board is uniformly distributed, and be sure
to include the proper sign for the torque.
