tracy stands on a skateboard and tosses her backpack to her friend who is standing in front of her. which best describes the acceleration tracy experiences? it is less than the acceleration of the backpack because she has a greater mass. it is greater than the acceleration of the backpack because she has a greater mass. it is less than the acceleration of the backpack because she uses a smaller force. it is greater than the acceleration of the backpack because she uses a larger force.
Answer
# Brief Explanations:
According to Newton's second - law $F = ma$ (force equals mass times acceleration). The force Tracy exerts on the backpack is equal in magnitude and opposite in direction to the force the backpack exerts on Tracy (Newton's third - law). Since Tracy has a greater mass than the backpack and $a=\frac{F}{m}$, with the same force acting on both, the object with greater mass has less acceleration.
# Answer:
It is less than the acceleration of the backpack because she has a greater mass.
