A stunt driver wants to make his car jump over eight cars parked side by side below a horizontal ramp(a) With what minimum speed must he drive off the horizontal ramp? The vertical height of the ramp is h = 1.5 m above the cars,and the horizontal distance he must clear is L = 17 m.m/s(b) If the ramp is now tilted upward, so that "takeoff angle" is 10° above the horizontal, what is the new minimum speed?m/s

1. A ball is thrown horizontally from the roof of a building 9.4m tall and lands 9.7m from the base. What was the balls initial speed? 2. You buy a plastic dart gun, and being a clever physics student you decide to do a quick calculation to find its maximum horizontal range. You shoot the gun straight up, and it takes 3.6s for the dart to land back at the barrel. What is the maximum horizontal range of your gun?...
