Two Dimensional Motion Test

When a ball is dropped off a cliff, which cliff will the ball have the shortest time of flight with?

The shortest cliff

Which way is a ball’s acceleration

Down

To increase the time of flight you

Increase the launch angle and increase the ball’s initial speed

If an angle of elevation is decreased, the vertical component of the ball’s initial elocity will

decrease and its horizontal component will increase

Sphere A is thrown at 40 m/s, Sphere B is thrown at 20 m/s both at the same time, which statement best describes the time required for the spheres to reach the ground and the horizontal distance they traveled?

Both spheres hit the ground at the same time, but sphere A lands twice as far as sphere B from the base of the tower

Increasing the height leads to

greater flight

Acceleration always

stays the same
