In a projectile motion we always have...

What is the vertical acceleration of a projectile?

A ball is thrown into the air at some angle. At the very top of the ball's path, its velocity is

At what point is v_y= 0 m/s?

At what point is v_x= 0 m/s?

Which vector pair (arrow pair) correctly represents the acceleration and velocity at point P?

Suppose Lemming A runs off the edge of the cliff at 2 m/s and Lemming B runs off the edge at 1 m/s. Which will hit the ground first?

Once a projectile is launched, what is the only force that affects its motion?

A projectile is fired horizontally from a height of 20 meters above the ground, with an initial velocity of 7.0 m/s. How far does the projectile travel horizontally before it reaches the ground?

A group of students wish to determine the launch speed of a specific 'launcher' device that they are using in a projectile experiment. The group is using the launcher to launch a ball horizontally from the top of their lab table, to land on the floor below. The group has already measured the height of the table, relative to the floor below. Which one of the following sets of additional measurements would be adequate to allow the group to determine the ball's launch speed, without taking any extraneous/unnecessary measurements?

In a lab experiment, a ball is rolled down a ramp so that it leaves the edge of the table with a horizontal velocity v. If the table has a height h above the ground, how far away from the edge of the table, a distance x, does the ball land? You may neglect air friction in this problem.

A diver moving horizontally with speed v dives from a cliff that is y meters high and lands a distance d from the base of the cliff. How far from the base of the cliff would the diver land, still going speed v, if the cliff were 4y meters high?

A projectile is fired with initial velocity vo at an angle θ with the horizontal and follows the trajectory shown above. Which of the following pairs of graphs best represents the vertical components of the velocity and acceleration. v and a, respectively, of the projectile as functions of time t?
