Problem 26PE

When landing after a spectacular somersault, a 40.0-kg gymnast decelerates by pushing straight down on the mat. Calculate the force she must exert if her deceleration is 7.00 times the acceleration due to gravity. Explicitly show how you follow the steps in the Problem-Solving Strategy for Newton’s laws of motion.

Step 1 of 3:

The gymnast pushes on the mat to reduce her acceleration after a somersault. The deceleration experienced by the gymnast is seven times the acceleration due to gravity. Our aim is to calculate the force exerted by the gymnast if she decelerates at the mentioned acceleration.

Mass of the gymnast

Acceleration experienced by the gymnast . Where g is the acceleration due to gravity,
