The fastest recorded pitch in Major League
Baseball was thrown by Nolan Ryan in 1974. If this pitch was thrown
horizontally, the fall would fall 0.809 m (2.65 ft) by the time it reached
home plate 18.3 m (60 ft) away. How fast was this pitch?
A shell is fired from the ground with an
initial speed of 1.70 x 103 m/s (approx. five times the speed of sound)
at an initial angle of 55.0° to the horizontal. Neglecting air
a) The amount of time the shell is in motion.
b) The shell’s horizontal range.
A spy in a speed boat is being chased down
a river by government officials in a faster craft. Just as the officials’
boat pulls up next to the spy’s boat, both boats reach the edge of a 5.0
m waterfall. If the spy’s speed is 15 m/s and the officials’ speed
is 26 m/s, how far apart will the two vessels be when they reach the bottom
of the waterfall?
