Problem 8--circular motion and projectile motion: tarzan (mass 80 kg) swings at the end of an 8.0-m long vine. when directly under the vines support, he releases the vine and files across a swamp. when he releases the vine, he is 5.0 m above the swamp and 10.0 m horizontally from the other side. determine the force the vine exerts on him at the instant before he lets go (the vine is straight down when he lets go).

1000 N

Explanation:

Let v be the his horizontal speed when he releases the vine and t be the time it takes for him to fly across the swamp and land.

Assume

When he releases the vine, there's only gravity acting on him downward. There's also no vertical velocity at this point.

Therefore, for him to travel 5 m vertically:

Horizontally we have

For Tarzan to achieve this horizontal speed, the centripetal acceleration and force exerting on the vine at the instant before he let go must be

it would be kevlar ^^

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
