Tarzan is swinging through the jungle on a vine that will break if the force exceeds 2.0 x 103 n. if the length of the vince is 5.0 m and tarzan's mass is 100. kg, what is the highest speed he can safely travel while swinging on the vine? hint: at what point in the swing will the tension in the vine be the greatest?

Given:

Force F = 2000 N

Mass, m = 100 kg

Length of the vine, R = 5.0 m

To determine:

The highest speed, v

Explanation:

The total force is given as:

F = mV²/R + mg

2000 = 100*V²/5 + 100*9.8

V² = 51

V = 7.14 m/s

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
