At bat a baseball player hits a ball at a height of .889 m. The ball leaves the bat at 51 m/s at an angle of 81 degrees from the vertical. The ball skims the top of a 2.74 m wall as it leaves the field.
a.) Draw position, velocity and acceleration graphs describing the ball between the hit and when it leaves the field. Assume t=0 when the ball is hit, up is positive, the ball moves in positive horizontal direction, and that the pitcher's mound is the origin.
b) How long it the ball in the air?
c.) How far away from home plate is the wall?
d.) What angle relative to the x-axis is the ball moving when it passes the wall?
e.)If an infield player can jump to get his mitt 2.74 m off the ground, how close to home plate was he to still catch the ball.
Please help, I'm so confused on most of this problem. I got the equations for x=Vosin(theta)t; delta y=Vocos(theta)+.5gt^2; and Vy=Vocos(theta)+at. I'm not sure how the fact that the origin is at the pitcher's mound affects the problem and I don't know how to solve for time. Thanks in advance!
