A Swinging Monkey A 8.72 kg monkey is hanging by one arm from a branch and swinging on a vertical circle. As an approximation, a
1 answer:
Answer:
Centripetal force, F = 66.36 N
Explanation:
Given that,
Mass of the monkey, m = 8.72 kg
The radial distance between the branch and the point where the monkey's mass is located to be 84.1 cm, r = 84.1 cm
The speed of the monkey, v = 2.53 m/s
We need to find the magnitude of the centripetal force acting on the monkey. It is given by :
So, the magnitude of the centripetal force acting on the monkey is 66.36 N.

Answer:
See bolded below.
Explanation:
Consider the " Before " and " After. " " Before, " this particle 1 was trying to catch up with this particle 2, and " after " particle one had collided with particle two. Take a look at the attachment below for a more detailed examination.
Here is how this will play out. Particle 1, with great velocity, will hit particle 2, which would mean that Particle 2 has less velocity than Particle 1. Now after the collision, energy is transferred to Particle 2, and while Particle 1 has now stopped in it's tracks, Particle 2 - with more energy than before - will continue as long as it has to before friction eventually brings it to a stop.

From this we can conclude that Vf, from the picture below, must have less energy than V1, but more energy than V2 - and vice versa.
Answer:
362.41 km/h
Explanation:
F = Force
m = Mass = 84 kg
g = Acceleration due to gravity = 9.81 m/s²
C = Drag coefficient = 0.8
ρ = Density of air = 1.21 kg/m³
A = Surface area = 0.04 m²
v = Terminal velocity
F = ma
Converting to km/h
The terminal velocity of the stone is 362.41 km/h
