i don't know why I am having trouble on this...
In one contest at the county fair, a spring-loaded plunger launches a ball at a speed of 3.50 m/s from one corner of a smooth, flat board that is tilted up at a 20 degree angle. To win, you must make the ball hit a small target at the adjacent corner, 2.45 m away. At what angle theta should you tilt the ball launcher?
a along the y-axis is: 3.3518m/s^2
i don't know what to do next... please help
i know that youre supposed to look at it when it reaches the top of its arc when
vf=0m/s
vi=3.5m/s
d= 1.225m
t=?
a(ball)=?
a (y-axis): 3.3518m/s^2
theta=?
