A remote-controlled toy car moves up a ramp and travels across a gap to land on another
ramp, as illustrated in Fig. 1.1.
The car leaves ramp P with a velocity of 5.5 m s–1 at an angle θ to the horizontal. The
horizontal component of the car’s velocity as it leaves the ramp is 4.6 m s–1. The car lands at
the top of ramp Q. The tops of both ramps are at the same height and are distance d apart.
Air resistance is negligible.
(i) Show that the car leaves ramp P with a vertical component of velocity of 3.0 m s–1.
