a. How long does it take the ball to reach the bottom of the cliff ?
100
False
An object which is thrown horizontally is called a trajectory

A ball is thrown horizontally at a speed of 10 m/s from the top of a cliff 78.4 m high.
How far from the base of the cliff does the ball strike the ground?
200
True
The greater the horizontal velocity at which a projectile is launched the greater the horizontal distance will be.

A truck traveling at 20 m/s rolls off the edge of a cliff. The cliff is 44.1 m above the ocean.
How far from the base of the cliff does the car strike the water?
300
False
The greater the horizontal velocity at which a projectile is launched the greater the time of flight will be.

A truck traveling at 20 m/s rolls off the edge of a cliff. The cliff is 44.1 m above the ocean.
How long does it take for the truck to hit the water.
400
True
On a projectile the velocity is constant horizontally.
