A baseball is thrown from an outfielder to the second baseman on a level field. The ball is in the air for a time At = 3.50 s and travels a horizontal distance of 92.0 m %3D before being caught at the same height it was thrown from. Ignore air resistance. a) What are the x- and y-components of the ball's initial velocity? b) What is the maximum height of the ball? c) When is the ball traveling at an angle of 0 = -26.0°?

A projectile is launched with an initial velocity of 28.6 m/s at 67.5 degrees with respect to the horizontal. What is the speed of the projectile 1.54 s after being launched. Assume the speed is measured in m/s.

A canon was launched with an initial speed of 104 m/s at an angle of 41.1° above the horizontal. The canon hit the top of a building that is 961 m away from where the canon was launched. What is the height of the building? 238.47 m 419.17 m 101.56 m 538.50 m

A baseball pitcher throws a pitch with an initial velocity of 45 m/s (100 mph!), directed horizontally. You will be asked to find how far the ball drops vertically by the time it crosses the plate 18.0 m away.  Find the time it takes for the ball to travel the horizontal distance to the plate.    2.5 s   0.40 s   4.6 s   0.22 s

A baseball is thrown toward a player with an initial speed of 36.6 m/s at 50⁰ with the horizontal. At the moment the ball is thrown, the player is 150 m from the thrower. At what average speed must he run toward the thrower to catch the baseball 0.914 m above the height at which it was released?
