Homework Statement
A man is riding on a flatcar traveling at a constant speed of 9.10m/s. He wishes to throw a ball through a stationary hoop 4.90m above the height of his hands in such a manner that the ball will move horizontally as it passes through the hoop. He throws the ball with a speed of 10.8m/s with respect to himself. What must the vertical component of the initial velocity of the ball be?
Homework Equations
y=y0+v0t+1/2gt^2
y=4.9?? ..not sure if that's right
y0=0
g=9.8
The Attempt at a Solution
i am pretty sure y=4.9
using this i solved t=v0/g
then i plugged what i had into the relevant equation
and i got v0=5.65 which is way off
please help! thanks!
