Average Force question (baseball, glove, bat)

[DLxX]

Please help me with this question

An outfielder catches a baseball of mass .14kg moving at 50m/s. The glove and ball move .50m during the time the ball is stopped. What is the average force exerted by the ball on the outfielder's glove?

At first I thought this questin had to do with F=ma, but the .50m part is confusing me.

Use the work-energy theorem instead

Yes, this question does involve F=ma, but it also incorporates the concept of work and energy. The .50m represents the distance over which the ball is stopped, and this work is done by the force exerted by the ball on the glove. To find the average force, we can use the equation W=F*d, where W is the work done, F is the force, and d is the distance. We know the work done is equal to the change in kinetic energy of the ball, so we can set W=ΔKE. We can also use the equation KE=1/2*m*v^2 to find the initial kinetic energy of the ball. From there, we can rearrange the equations to solve for the average force. I hope this helps!
