Question

An acrobat with a mass of 41-kg jumps on a trampoline.

What force does a trampoline have to apply to accelerate her straight up at 7.5 m/s^{2} in Newtons? |

Step 1

Given:

Mass of acrobat, m = 41 kg

Acceleration of acrobat, a = 7.5 m/s^{2 }

Acceleration due to gravity, g = 9.8 m/s^{2}

Let force applied by trampoline be R.

Step 2

Step 3

There is no force acting along X- axis.

From Newton’s s...
