Problem 18PE
What force does a trampoline have to apply to a 45.0-kg gymnast to accelerate her straight up at 7.50 m/s2 ? Note that the answer is independent of the velocity of the gymnast—she can be moving either up or down, or be stationary.
Step-by-Step Solution:
Solution 18PE
We are required to calculate the force on the gymnast that a trampoline would apply to her if she has an upward acceleration.
Step 1 of 2
The acceleration due to gravity m/s2
The upward acceleration of the gymnast 7.50 m/s2
Therefore, the net acceleration of the gymnast m/s2
m/s2
Step 2 of 2
