An object is launched at a velocity of 15 m/s in a direction making an angle of 30° upward
with the horizontal. What is the maximum height reached by the object? (g-9.81)
A) 1.87 m
B) 2.87 m

Tarzan, in one tree, sights Jane in another tree. He grabs the end of a vine with length 20 m that makes an angle of 45° with the vertical, steps off his tree limb, and swings down and then up to Jane’s open arms. When he arrives, his vine makes an angle of 30° with the vertical. Determine whether he gives her a tender embrace or knocks her off her limb by calculating Tarzan’s speed just before he reaches Jane. Ignore air resistance and the mass of the vine.
In soccer, explain the difference when you shoot from a static position to a moving/running kick?

The initial speed of the Juggernaut is vJi and the initial speed of Colossus is vCi. After the collision, the final speed of the Juggernaut is vJf and the final speed of Colossus is vCf as they each bounce off of the other, heading in opposite directions. a. What is the impulse experienced by the Juggernaut? b. What is the impulse experienced by Colossus? c. In your own words, explain how these impulses must compare with each other and how they are related to the average force each superhero experiences during the collision.arrow_forward1) A marble launcher fires a marble at an angle of 50° to the horizontal with an initial velocity of 6.2 m/s.

The feather impacts the Earth first because the force of gravity is weaker on the lighter feather. The hammer and feather both impact the ground at the same time. The hammer impacts the ground first because it is heavier than the feather. The feather hits the ground after the hammer because of air resistance.arrow_forward
- After being hit with a white ball, the black 8 ball moved 12.78 inches at an angle of 35° N of E from its resting position. Once it strikes the side of the billiard table, it bounced off an angle of 41° W of N and traveled 30.9 inches, and after striking the side of the table again, traveled another 5.030 inches at an angle of 45° S of W before coming to a full stop.
