Number 3 Please.
For each of the following, solve the problem and create a graph showing the position of the bullet of the gun and the monkey at the same points in time. A monkey is in a tree 30 meters above the ground. The hunter is 40 meters away and has a gun that shoots at 60 m/s. How far will the monkey fall before being hit? 2. A hunter stands 18 meters away from a tree with a...

Projectile Motion Gun sights are adjusted to aim high to compensate for the effect of gravity, effectively making the gun accurate only for a specific range. If a gun is sighted to hit targets that are at the same height as the gun and 70.0 m away, how low will the bullet hit if aimed directly at a target 91.0 m away? The muzzle velocity of the bullet is 270.0 m/s. (Discuss qualitatively how a larger muzzle velocity would affect...

1)A bullet is fired vertically upward from a gun with an initial velocity of 235 m/s. How high does the bullet go? How long does it take to reach its maximum height? How long is it in flight? 2)Calculate the kinetic energy of a 0.350 kg baseball thrown at a velocity of 36.0 m/s.

- Part A-An apple falls from a tree and drops straight to the ground. Its initial height was 1.1 m, and its speed just before hitting the ground was 3.5 m/s. If air resistance does -8.0x10-2 J of work on the apple, what is the mass of the apple? 2.5x10-2 kg 1.7x10-2 kg 4.7x10-3 kg 3.2x10-2 kg

Tarzan grabs a vine hanging vertically from a tall tree when he is running at 9.2 m/s. (a) How high (in m) can he swing upward? (Enter your answer with respect to the ground.) (b) Does the length of the vine affect this height? The length of the vine does affect this height. The length of the vine does not affect this height.

If a projectile is fired with an initial velocity of vo meters per second at an angle a above the horizontal and air resistance is assumed to be negligible, then its position after t seconds is given by the parametric equations x = (vo cos(a)t y = (vo sin(a)t - +- 1012 where g is the acceleration due to gravity (9.8 m/s2). (Round your answers to the nearest whole number.) (a) If a gun is fired with a = 30°...
