A cannon is fired with an initial horizontal velocity of 20 m/s and initial vertical velocity of 25 m/s. After 3s in the air, the canon hits its target. How far away (in meters) was the canon from its target? Answer: m

Ignoring air resistance, a helicopter is flying with a velocity of 90 m/s at an angle of 23 degrees above the horizontal. When the helicopter is 114 m directly above a dog that is standing on level ground, they dropped a crate. How far from the dog will the crate land?

A projectile is launched from point A with speed vo = 39 m/s. Determine the value of the launch angle a which maximizes the range R indicated in the figure. Determine the corresponding value of R. Vo = 39 m/s Answers: a= A/α R = i i 49 m R O 11 m m B

A batter hits a fly ball with an initial velocity of 37 m/s at an angle of 32° from the horizontal. How much time does the outfielder have to get to the appropriate position to catch the ball?

A projectile is thrown from the top of a cliff with an initial speed of 25 m/s at an angle of 600 up from the horizontal. If the projectile lands 100 m from the base of the cliff how tall is the cliff?

An arrow is shot from a height of 1.4 m toward a cliff of height H. It is shot with a velocity of 26 m/s at an angle of 60° above the horizontal. It lands on the top edge of the cliff 3.4 s later. The height H of the cliff is

A projectile is fired from the ground, reaches a maximum height of 40.4 m and lands a distance of 22.9 m away from the launch point. What was the projectile s launch velocity? 28.2 m/s, 41.0 degrees above horizontal 4.0 m/s, 41.0 degrees above horizontal 51.1 m/s, 20.5 degrees above horizontal 28.4 m/s, 81.9 degrees above horizontal

A father demonstrates projectile motion to his children by placing a pea on his fork's handle and rapidly depressing the curved tines, launching the pea to heights above the dining room table. Suppose the pea is launched at 7.55 m/s at an angle of 71.0° above the table.   With what speed (in m/s) does the pea strike the ceiling 2.10 m above the table? Find M/S

A projectile is fired from the edge of a cliff, with an initial speed of 185 m/s at an angle of 40.0° above the horizontal. The projectile rises and then falls into the sea next to the cliff. The height of the cliff measured from the sea level is h. The time of flight of the projectile until it hits the water is 40.0 s. Ignore air resistance. What is the height h of the cliff? What is the maximum height the projectile has reached (measured from the seal level)? What is the magnitude of the ball's velocity just before it hits the ground?

A ball is thrown vertically upward with an initial speed of 88 ft/sec from the base A of a cliff with H = 60 ft. Determine the distance h by which the ball clears the top of the cliff and the time t after release for the ball to land at B. Also, calculate the magnitude of the impact velocity vg. Neglect air resistance and the small horizontal motion of the ball. Answers: h = i ft t = i sec VB = i ft/sec
