A baseball player hits a homerun, and the ball lands in the left field seats, which is 103m away from the point at which the ball was hit. The ball lands with a velocity of 20.5 m/s at an angle of 38 degrees below horizontal. Ignoring air resistance
(a) Find the initial velocity and the angle above horizontal with which the ball leaves the bat
(b) Find the height of the ball relatively to the ground.

Afaulty model rocket moves in the xy-plane (the positive y direction is vertically upward). the rocket's acceleration has components ax(t) = ? t2 and ay(t) = ? ? ? t, where ? = 2.50 m/s4 , ? = 9.00 m/s2 , and ? = 1.40 m/s3 . at t = 0 the rocket is at the origin and has velocity ~v0 = v0x ? i + v0y ? j with v0x = 1.00 m/s and v0y = 7.00 m/s. (a) calculate the velocity and position vectors as functions of time. (b) what is the maximum height reached by the rocket? (c) sketch the path of the rocket. (d) what is the horizontal displacement of the rocket when it returns to y = 0?
