What force does a trampoline have to apply to a gymnast to accelerate her straight up at ? Note that the answer is independent of the velocity of the gymnastâshe can be moving either up or down, or be stationary.

Force applied by trampoline = 778.5 N

Note: The question is incomplete.

The complete question is : What force does a trampoline have to apply to a 45.0 kg gymnast to accelerate her straight up at 7.50 m/s^2? note that the answer is independent of the velocity of the gymnast. She can be moving either up or down or be stationary.

Explanation:

The total required the trampoline by the trampoline = net force accelerating the gymnast upwards + force of gravity on her.

= (m * a) + (m * g)

= m ( a + g)

= 45 kg ( 7.50 *  9.80) m/s²

Force applied by trampoline = 778.5 N
