A stunt driver wants to make his car jump over eight cars parked side by side below a horizontal ramp. With what minimum speed must he drive off the ramp? The vertical height of the ramp is 1.5m above the cars, and the horizontal distance he must clear is 20m.
A projectile leaves the ground at 150 m/s and reaches a maximum height of 0.57 km. If there was no air resistance, at what angle above the horizontal did it leave the ground?
A projectile is fired with an initial speed of 40 m/s at angle of 23 degrees above the horizontal on a long flat firing range. Determine (1) the maximum vertical distance reached by the projectile, (2) the total time in the air, (3) the range of the projectile, (4) the velocity of the projectile 2 s after firing.
