Projectile Motion Lesson

A ball is projected at an angle with an initial horizontal velocity of 8.0 m/s and an initial vertical velocity of 29.4 m/s. The trajectory diagram shows the position of the ball after each consecutive second.

What is the horizontal velocity of the ball after 6 seconds?

A ball is projected at an angle with an initial horizontal velocity of 8.0 m/s and an initial vertical velocity of 29.4 m/s. The trajectory diagram shows the position of the ball after each consecutive second.

What is the vertical velocity of the ball after 6 seconds?

Two spheres, A and B are simultaneously projected horizontally from the top of a tower. Sphere A has a horizontal velocity of 40m/s and Sphere B has a horizontal velocity of 20m/s. Which statement best describes the time required for the spheres to reach the ground and the horizontal distance they travel?

Two spheres of equal mass, A and B, are projected off the edge of a 2.0 m high bench. Sphere A has a horizontal velocity of 5.0 m/s, and sphere B has a horizontal velocity of 2.5 m/s. If both spheres leave the table at the same instant, ball A hits the floor at the spot marked X. Where will ball B hit the floor?

Two spheres of equal mass, A and B, are projected off the edge of a 2.0 m high bench. Sphere A has a horizontal velocity of 5.0 m/s, and sphere B has a horizontal velocity of 2.5 m/s. Which ball will be in the air for the greater amount of time?

The diagram to the left shows the trajectory (path) of a kicked football. At the point labeled X, what can be stated about the vertical velocity component of the football’s motion?

An object is undergoing free fall motion. As it falls, the object's ____.

At what point in its path is the horizontal component of the velocity (v_x) of a projectile the smallest?

At what point in its path is the vertical component of the velocity (v_y) of a projectile the smallest?

If a projectile is launched horizontally with a speed of 12.0 m/s from the top of a 24.6-meter high building. Determine the horizontal displacement of the projectile.

A projectile is launched horizontally from the top of a 45.2-meter high cliff and lands a distance of 17.6 meters from the base of the cliff. Determine the magnitude of the launch velocity.

In an effort to create a cannonball-style splash, eight-year old Matthew runs off the edge of the board of the high dive at 4.6 m/s and falls 2.3 m to the water below.

Determine the time for Matthew to fall the 2.3 m to the water.

In an effort to create a cannonball-style splash, eight-year old Matthew runs off the edge of the board of the high dive at 4.6 m/s and falls 2.3 m to the water below.

What horizontal distance from the edge of the board will Matthew plunge into the water?

In an effort to create a cannonball-style splash, eight-year old Matthew runs off the edge of the board of the high dive at 4.6 m/s and falls 2.3 m to the water below.

With what speed (resultant velocity) does Matthew enter the water?

An emergency relief plane is dropping a care package from a plane to a group of medical personnel working for a relief agency in an African village. The package is designed to land in a small lake, inflate an attached raft upon impact, and finally resurface with the raft side down. The plane will be moving horizontally with a ground speed of 59.1 m/s. The package will be dropped a horizontal distance of 521 m from the intended target location. At what altitude above the pond must the plane be flying in order to successfully accomplish this feat?
