Abowling bowl is thrown off the top of a building. determine distance the ball has fallen after falling for 3.0 s. remember, the gravitational acceleration (g) is 9.8 m/s2. (hint: d = ½gt2)

That "hint" gives the whole thing away.  It's like asking "What color is an orange ?"

All you have to do is take the formula in the 'hint', write the numbers that you know in place of the letters, turn the crank, and catch the answer when it falls out onto the floor.

The question GIVES you ' g '  and  ' t '.  Just wrightum into the formula.

I got 44 meters in my head.  You'll have to check that.
