Abatter hits a softball over a third baseman's head with speed v0 and at an angle ? from the horizontal. immediately after the ball is hit, the third baseman turns and runs at a constant velocity v=7.000m/s, for a time t=2.000s. he then catches the ball at the same height at which it left the bat. the third baseman was initiallyl=18.00m from home plate (the location where the ball was hit from).
a) find v0. use g=9.807m/s2 for the magnitude of the acceleration due to gravity. assume that there is no air resistance.
b) find the angle ? in degrees.
c)find the components vxand vy of the ball’s velocity, v, 0.100 s before the ball is caught.
d)find the vector components x and y of the ball’s position, r, 0.100 s before the ball is caught.
