Question

local team drafts pitcher who consistently throws 43.35 m/s (97.00 mph). Assume the mass has 0.1422 kg and has this speed before batter makes contact. How much kinetic energy in Joules?
How high would the ball have to be dropped from to attain same energy? Neglect air resistance and acceleration due to gravity is 9.81 m/s Answer is in m local team drafts pitcher who consistently throws 43.35 m/s (97.00 mph).

Explanation / Answer

a) KE = 0.5*mv^2

KE = 0.5*0.1422*43.35^2

KE = 133.6127 J

b) E = mgh

133.6127 = 0.1422*9.8*h

h = 95.88 m
