On planet Fuud an object dropped (initial velocity=0) from 100 feet hits ground after 5 seconds. Noe that you are expected to do this exercise using only the knowledge generated in the first chapter of our text, not some other more advanced formulas that can be found. I.e. only formula used should be that of the basic height function: y(t) =gt + vot + yo. a. Find the gravitational constant for planet Fuud. b. Fred visits planet Fuud and finds that he can throw a ball (straight up) as high as 80 feet while there (and no higher), how high up is Fred able to throw this ball on planet Earth? Assume the initial height from which Bill throws the ball is 0 feet. Hint: first find the initial velocity with which Fred can throw the ball.
