Determine the maximum height reached by the projectile. Determine the maximum horizontal distance covered by the projectile. Determine the velocity of the projectile just before it hits the bottom of the cliff. A projectile is fired from the edge of a cliff 20 m high with an initial speed of 12 m/s at an angle of 41 above the horizontal. Determine the total time in the air. Determine the maximum height reached by the projectile. Determine the maximum horizontal distance covered by the projectile. Determine the velocity of the projectile just before it hits the bottom of the cliff.
