A bullet is shot horizontally from a gun. If the bullet speed as it exits the muzzle is 325 m/s and the gun is 2.0 m above the ground
a. How long was a bullet in the air for?
b. How far did the bullet travel horizontally before it hit the ground?
c. What is the final velocity of the bullet?
A small ball rolls horizontally off the edge of a tabletop that is1.20 m high. It strikes the floor at a point 1.68 m horizontallyaway from the edge of the table. (a) How long is the ball in theair? (b) What is its speed at the instant it leaves thetable?
An object rolls off a table top with a horizontal velocity v0x = 3.4 m/s. The table is at a height y0 = 0.45 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.
