Question

june, melissa, and anna have skateboards that are the same mass. they were playing with their skate
when another skateboard came along and bumped their skateboards, but not from the same direc
teboard changed speed as a result of being bumped. use the information in the diagram to answer.
ch skateboard(s) experienced the strongest force when bumped? how do you know?
a the green skateboard experienced the strongest force because it changed speed the most.
b the green skateboard experienced the strongest force because it takes a stronger force to slow
down than it takes to speed something up.
c the red and brown skateboards experienced the same strength force because they both gaine
the green skateboard lost force.
d the red skateboard experienced the strongest force because it has the fastest ending speed.

Explanation:

According to Newton's second law \(F = ma\) (where \(a=\frac{\Delta v}{\Delta t}\), and assuming the time of interaction \(\Delta t\) is the same for all skate - boards since the collision time is the same for the event). Since the mass \(m\) of the skate - boards is the same, the force \(F\) is proportional to the change in velocity \(\Delta v\). The green skate - board has the largest \(\Delta v\) (change in speed).

Answer:

A. The green skateboard experienced the strongest force because it changed speed the most.
