A cart launches a ball 15cm high. The vertical distance from the lowest ball to the highest is about two cart heights or 30cm.(adsbygoogle = window.adsbygoogle || []).push({});

Estimate the launch speed of the ball?

Estimate the time interval between successive stroboscopic exposures?

I honestly have no idea where to begin with either problem even after thoroughly reading the chapter where it is supposedly covered.

Does the equation y=h-(1/2)(g)(x/v0)^2 have anything to do with the problem?
