23. * * EST You drop a 78-g ball vertically onto a force sensor that is 0.4 m below the ball's initial position. The ball bounces off the force sensor after the collision. Figure P6.23 shows the time dependence of the force exerted by the ball on the force sensor. Estimate the expected peak magnitude of the force. Indicate any assumptions that you made, and discuss how they affect the estimated peak value. (Hint: The area under the force-versus-time curve has approximately the shape of a triangle.)
