A billiard ball is rolling across a pool table towards the front of a train at 2.2m/s while the train is moving forward at 6.3m/s.  How fast is the ball moving relative to the ground? Later the ball is rolling toward the back of the train at the same speed. What is the ball's velocity relative to the ground now?

A ball is rolled horizontally off a table with an initial speed of 0.24 m/s. A stopwatch measures the ball's trajectory time from table to the floor to be 0.30 s. How far away from the table does the ball land? (g = 9.8 m/s2 and air resistance is negligible).

A cannonball is launched horizontally off a 50 m high castle wall with a speed of 20 m/s. What is the range of the cannonball?

You throw a ball  straight up in the air with a velocity of 60 m/s on a planet where the acceleration due to gravity is 15 m/s^2 A) what is the velocity of the ball after four seconds? B) how long does it take before the ball lands back in your hand?

OK, this is the last time for one of these crazy adventures. THIS time, though, there is a window in the floor, and you can see that you re in a rocket which has just taken off from the surface of an alien planet. By taking careful measurements out that window you determine that the rocket is accelerating upward at 7.42 m/s^2. When you drop a ball from a height of 1.74 m, it hits the floor 0.254 s later. What is the value of g for the alien world below you? 1. 63.8 m/s^2 55.2 m/s^2 3 79.1 m/s^2 4 46.5 m/s^2

THIS time, though, there is a window in the floor, and you can see that you re in a rocket which has just taken off from the surface of an alien planet. By taking careful measurements out that window you determine that the rocket is accelerating upward at 9.60 m/s^2. When you drop a ball from a height of 1.20 m, it hits the floor 0.362 s later. What is the value of g for the alien world below you?     16.5 m/s^2     8.7 m/s^2     28.1 m/s^2     18.4 m/s^2

THIS time, though, there is a window in the floor, and you can see that you re in a rocket which has just taken off from the surface of an alien planet. By taking careful measurements out that window you determine that the rocket is accelerating upward at 7.11 m/s^2. When you drop a ball from a height of 1.08 m, it hits the floor 0.213 s later. What is the value of g for the alien world below you?     49.0 m/s^2     60.8 m/s^2     40.5 m/s^2     57.4 m/s^2

An arrow is shot from a height of 1.95 m toward a cliff of height H. It is shot with a velocity of 33 m/s at an angle of 60° above the horizontal. It lands on the top edge of the cliff 3.85 s later. What is the height H of the cliff in m? What is the maximum height reached by the arrow along its trajectory in meters? What is the arrow's speed just before hitting the cliff in m/s?

A boat traveling 37 m/s is approaching a waterfall. The waterfall is 50 meters high. How far does the boat travel horizontally before striking the water?

A Doctors without Borders Cargo plane drops a large package of relief medical supplies as it is moving with a horizontal velocity vx = 250. m/s at a height above the flat ground of y=693m. What is the y component of the final velocity of the package in m/s just before it hits the ground?
