A shot putter releases the shot some distance above the level ground with a velocity of 12.0 m/s, 51.0° above the horizontal. The shot hits the ground 2.08 s later. Ignore air resistance. (a) What are the components of the shot’s acceleration while in flight? (b) What are the components of the shot’s velocity at the beginning and at the end of its trajectory? (c) How far did she throw the shot horizontally? (d) Why does the expression for R in Example 3.8 not give the correct answer for part (c)? (e) How high was the shot above the ground when she released it? (f) Draw x - t , y - t , υ x - t , and υ y - t graphs for the motion.

Jack Sparrow stands on top of a cliff 82.0m tall and throws a rock with an initial velocity of 28.0m/s at an angle of 15.0° below the horizontal. a) How far from the base of the cliff will rock land? b) What will be the velocity of the rock when it reaches the ground?
In projectile motion lab, you fired a projectile out of your launcher vertically up at 5.0
m/s. Assume the projectile leaves the launcher's barrel at 1.15 m above the floor and
has a tiny horizontal velocity so it could clear the launcher on its way down and hit
the floor, how long will it take to strike the floor?
Ignore air drag.
Hint: You can set the final position to be zero.
A baseball pitcher throws a ball at 98.0 mi/h in the horizontal direction. How far does the ball fall vertically by the time it reaches home plate, which is a
horizontal distance of 60.5 ft away? (Express your answer in units of feet. Neglect air resistance.)
ft
A mountain lion jumps to a height of 3.30 m when leaving the ground at an angle of 41.5°. What is its initial speed (in m/s) as it leaves the ground?
m/s
