When an object is launched from the ground with an initial velocity of V0 at an angle of , the horizontal and vertical displacements of the object travel before it hits ground can be written as functions of time t : X(t) = V0 *t*cos () Y(t) = V0 *t*sin () 1/2 *g* t^2

A baseball has been tossed with the initial velocity 15 m/s with the angle 30o from the ground. Use g = 9.81 m/s2 and t from 0 to 1.52 seconds.

a) Plot the functions X and Y verse time t (i.e. X-t and Y-t graphs) on a same graph. b) Plot the trajectory of the baseball (ie. Y v.s. X graph). answer this question using matlab
