A pitcher throws a baseball horizontally from the mound to home plate. The ball falls 0.995 m (3.26 ft) by the time it reaches home plate 18.3 m (60 ft) away. How fast was the pitcher's pitch?

A ball is dropped from rest and falls for 5 s. What are its position and velocity at that instant? So the variables I can define are v1=0, v2= x t=5 Other than that I don't know what to do in this problem. I'm assuming position is the height so I'm looking

An outfielder throws a 0.145 kg baseball to the shortstop with a speed of 30 m/s at an angle of 20 degrees above the horizontal. How far does the ball travel? (Assume the shortstop catches it at about the same height that the outfielder throws it.)

if you drop an object from a height of 0.8m, it will hit the ground in 0.40s. if you throw a baseball horizontally with an initial speed of 29m/s from the same height, how long will it take the ball to hit the ground
