A baseball is accelerated from rest at the rate a = 251 m/s/s along a rising ramp of lenth l=3m. The ramp makes an angle of theta =.5 rad with the horizontal. Neglect friction. a)what is the launch velocity v knot of the ball? express v knot in a component form using a coordinate system of your choice. Sketch the ramp and show v knot and your coordinate system. b) how far down the range x from the launch point does teh ball land? c) suppose a wlal of heigh h stands at a distance d=x-31 m down range from the launch point. If the ball sails over the wall, waht is the maximum wall height?
