You throw a baseball at an initial speed of 15.0 m/s at an angle of 30° with respect to the horizontal. What would the ball’s initial speed have to be at 30° on a planet that has twice the acceleration of gravity as Earth to achieve the same range? Consider launch and impact on a horizontal surface.

A tennis ball is hit with a vertical speed of 35 m/s and a horizontal speed of 25 m/s. How long will the ball remain in the air?How far will it travel horizontally during this time?

A paper ball is flicked at a 10 degree angle off of a table. The center of the ball is measured to be 1.018 meters from the ground at the time of the launch, and lands on the ground 1.600 meters away. What is the launch speed of the paper ball?

An object rolls off a tabletop with a horizontal velocity v0x = 18 m/s. The table is at a height y0 = 0.75 m, above the floor. Use a coordinate system with its origin on the floor directly beneath the point where the object rolls off the table, its horizontal x-axis lying directly beneath the object’s trajectory, and its vertical y-axis pointing up. What is the vertical component of velocity, in meters per second, when the object hits the ground?

jon kicks a soccer ball with an initial horizontal velocity of 15 m/s. Dwight kicks a soccer ball with an initial horizontal velocity of 19 m/s. Whos esoccer ball will have traveled further horizontally after 2 seconds in the air?

A track star in the broad jump goes into the jump at 12 m/s and launches himself at 20° above the horizontal. How long is he in the air before returning to Earth? (g = 9.8 m/s2).

A rescue plane is flying at a speed of 98 m / s at 353 meters above the ground. If you drop a box of supplies, how far will it travel horizontally?

A ball is thrown from the top of a 35 meter high tower at a velocity of 60 m/s and at an angle of 25o above the horizontal.  How far from the base of the tower does the ball land?     What is its velocity just as it strikes the ground?

An object rolls off a tabletop with a horizontal velocity v0x = 18 m/s. The table is at a height y0 = 1.2 m, above the floor. Use a coordinate system with its origin on the floor directly beneath the point where the object rolls off the table, its horizontal x-axis lying directly beneath the object’s trajectory, and its vertical y-axis pointing up. What is the vertical component of velocity, in meters per second, when the object hits the ground?

San Francisco Giants mascot Lou Seal is trying to shoot t-shirts into the crowd at Oracle Park. Lou wants to deliver a t-shirt into the hands of a fan standing 40 m away horizontally but 16 m above the launch point. If he angles the t-shirt cannon 45 degrees above the horizontal, what speed does the cannon need to launch at to get the t-shirt to the fan? (You can ignore air resistance in this problem).
