(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

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?

2. Relevant equations

y=y0+v0t+1/2gt^2

y=4.9?? ..not sure if that's right

y0=0

g=9.8

3. 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!!!!!!!!!!!!!
