1. Problem
The kicker stands 50 m from the goalpost that is 3 m high. She kicks with an initial velocity of 24.5 m/s. She just makes the goal height-wise, but did the ball travel far enough? She kicked at an angle of 35.28 degrees.
2. Homework Equations
S = (1/2)at^2 + V0t + S0
S =V0xt (when V0x is constant)
3. What I Did
24.5cos(35.28) = V0x = 20
24.5sin(35.28) = V0y = 14.15
-5t^2 + 14.15t + 0 = 3
t = 2.6
20*2.6 = 52 m
2 meters to spare
The answer is 1.12 m to spare. Any help would be appreciated! Thanks.
