A golf ball starts with an initial velocity of 100m/s and slows at a constant rate of -8m/s2, what is its final velocity after 2
1 answer:
Answer:
<em>Answer: B. 84 m/s</em>
Explanation:
<u>Uniform Speed Motion</u>
It's a type of motion in which the velocity of an object changes by an equal amount in every equal period of time thus, the acceleration is constant.
Being a the constant acceleration, vo the initial speed, vf the final speed, and t the time, the final speed is calculated as follows:
The golf ball starts with an initial speed of 100 m/s and slows down at a=-8\ m/s^2. We are required to find the final speed at t=2 s:
Answer: B. 84 m/s

b)150.78N
Explanation:
Having in mind the conservation of energy, as the monkey goes up (gaining potential gravitational energy) the kinetic energy must be reduced, so reducing the velocity of the monkey. So the maximum velocity will be at this lower point with a velocity of 1.36m/s
From this velocity and the radius we can calculate the angular velocity for the monkey center of mass:
with this we can calculate the centripetal force magnitude:
On the mokey center of mass we have two opposite forces acting, the tension of the arm and the weight, in order for the monkey to continue swinging the resolt of this two forces must be equal to the centripetal force:
