In Fig. 4-40, a ball is launched with a velocity of magnitude
10.0 m/s, at an angle of 50.0° to the horizontal. The launch point is at
the base of a ramp of horizon-
tal length d = 6.00 m and
height d, = 3.60 m. A plateau
is located at the top of the
ramp. (a) Does the ball land on
the ramp or the plateau? When
it lands, what are the (b) mag-
nitude and (c) angle of its dis-
placement from the launch point?
