Question1

A painter of mass 140.0 kg stands on a platform of mass 55.0 kg and pulls on two ropes that hang over pulleys, as shown. He pulls each rope with a force of 50.0 N. assume a coordinate system where +y is up, compute the y-component of acceleration ay. ay can either be positive or negative depending on direction of the acceleration.

Question2

The drawing shows a skateboarder moving at 5 m/s all along a horizontal section of track that is slanted upward by 48° on top of horizontal at its end that is 0.44 m on top of ground. When she leaves the track, she follows characteristic path of projectile motion. Overlooking friction and air resistance, find out highest height H to which she rises above the end of the track.
