1) two blocks, each of mass m=2.80kg are hung from the ceiling of an elevator. If the elevator moves with an upward acceleration a of magnitude 1.9m/s^2, find the tensions T1 and T2 in the upper and lower strings.

2) A block of mass 1.15kg is pushed up against a wall by a force P that makes an angel of theta=50.0 degree angle with the horizontal as shown below. The coefficient of static friction between the block and the wall is 0.289. Determine the possible values for the magnitude of P that allow the block to remain stationary.
