A bowling ball rolls off of a 2.00 meter tall table. It hits the ground 1.50 meters from the edge of the table.(Answer to 3 sig figs) What was the launch speed?_____ m/s What was the time in flight? _____ sec
It leaves the table traveling at 2.35 m/s and falls for 0.639 s.
This is a projectile motion problem. I will use the vertical motion to find the time in flight first, then I will calculate the launch speed. I think it is easiest this way.
Like any object that falls 2.00 m, the time required comes from
In this case,
To travel 1.50 m in 0.639 s, the initial speed must have been
