Jackie Chan jumps from the top of one building to the top of another building 6.61 m away. After a running start, he leaps at a velocity of 4.0 m/s at an angle of 18.2° with respect to the flat roof.  What is the maximum difference in height that the second building must be in order for Jackie to make it across safely? (Make it positive.)

The figure below shows a ball thrown from the top of a cliff at a downward angle of θ= 35.9° . It hits the ground a distance D= 7.64 m from the base of the cliff at time t= 1.11 s. What was the initial speed v0 of the ball? Express your answer in m/s to 3 significant figures. Use g=9.81 m/s2.

A horizontal projectile is shot with an initial velocity of 29.9 m/s from a height of 6.99 m above the ground. Neglecting air-resistance, what is the direction of the final velocity (in degrees)? Hint: angle measured from the horizontal (+x-axis), positive angles for counterclockwise & negative angles for clockwise.

A dog jumps in a horizontal direction with an initial speed of vo=3.2 m/s from the edge of a table and lands L=2.3 m away from the table. a.hold long does it take the dog to hit the ground? (3 sig fig) b.what is the height in meters of the table? (3 sig fig)

An archer aims at a target that is a horizontal distance 55.0 m away and 5.0 m above the ground. The archer launches her arrow from of height of 1.5 m off the ground, and the arrow hits the target. The arrow is completely horizontal after sticking to the target (i.e., the arrow was traveling horizontally just before hitting the target). What was the initial speed of the arrow, in m/s?

A ball is shot with a velocity of 32 m/s at an angle of 28° from the top of a 18 m tall building. What is the horizontal distance the ball travels when it hits the ground?

the leprechaun in the shamrock patch was named O'Malley and since he was disrupted from sitting in his patch he decided to go off and play a round of his favorite sport in where leprechaun kick a gold coin from a tee into a post 317m away. if he kicked the coin at an angle of 60 degree at a velocity of 60 m/s how high was the arch of the rainbow created by the trajectory? how long did it take to get to the pot? the officials in dublin decided to add a goal post to "kick O coin" 300 meters away and so many 33 meters high. would O'Malley's kick have cleared this goal post?

Someone throws a ball with an initial speed of 3.13 m/s at a 30.0° angle above the horizontal. How long does it take it to reach its maximum height?

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 7.51 m/s at an angle of 81.0° above the table. With what speed (in m/s) does the pea strike the ceiling 1.90 m above the table?    m/s

The best leaper in the animal kingdom is the puma, which can jump to a height of 12.7 ft when leaving the ground at an angle of 50°. With what speed, in SI units, must the animal leave the ground to reach that height?
