1- What force in Newtons does a trampoline have to apply to a 50-kg gymnast to accelerate her straight up at 7,0 m/s^2? Note that the answer is independent of the velocity of the gymnastshe can be moving either up or down, or be stationary.
2- Suppose a 55-kg gymnast climbs a rope. What is the tension in the rope in Newtons if he accelerates upward at a rate of 1,0 m/s^2?
