V = Vo + g*Tr = 0 @ max ht.
Tr = -Vo/g = -17.5/-9.8 = 1.79 s. = Rise
time.
Tf = Tr = 1.79 s. = Fall time.
Tr + Tf = 1.79 + 1.79 = 3.58 s = Time in
flight.
d = Vc*(Tr+Tf) = 17.5 * 3.58 = 62.7 m.
You are traveling in a convertible with the top down. The car is moving at a constant velocity of 17.5 m/s, due east along flat ground. You throw a tomato straight upward at a speed of 13.0 m/s. How far has the car moved when you get a chance to catch the tomato?

hf=hi+1/2 g t^2 + vit
hf, hi=0
t= 2vi/g
horizontal distance= t*17.5m/s
hf, hi=0
t= 2vi/g
horizontal distance= t*17.5m/s
