how do you show the work for this The skateboarder in the drawing starts down the left side of the ramp with an initial speed of 4.0 m/s Neglect all nonconservative forces, such as friction and air drag. What is height h (above the rim) of the highest point reached by the skateboarder on the right side of the ramp? How high can he reach on the left side of the ramp when he come back? Explain why A 10 kg monkey is lunging by one arm from a branch and is swinging on a vertical circle As an approximation, assume a radial distance of 85 cm between the branch and the point where the monkey's mass is located. As the monkey swings through the lowest point on the circle, it has a speed of 3.0 m/s. Find the magnitude of the centripetal force acting on the monkey, and the magnitude of the tension in the monkey's arm [BONUS] Under these conditions, would the monkey be able to make a full circle swing around the branch? A satellite is in a circular orbit about the earth = 5.98 times 1024 N.m^2/Kg^2). The period of the satellite T =1.20 times 10^4 s, and the universal gravitational constant is G = 6.67 times 10^-11" N.m^2/kg^2. What is the speed which the satellite travels? [ BONUS] What is the total mechanical energy of the satellite?Explanation / Answer
as per guide lines i am doing first question
from the conservation of energy
1/2 mv^2 = mgh
h = v^2/ 2g
=( 4)^2/ 2( 9.8)
=0.81 m
-----------------------------------------------
(b)
1/2 mvi2 + mghi = 1/2 mv^2 + mghf
mg( 0.891 m) = 0+ mghf
hf = 0.891 m
