A box of canned goods slides down a ramp from street level into the basement of a grocery store with acceleration 0.65 m/s2 directed down the ramp. The ramp makes an angle of 35 degrees with the horizontal. What is the coefficient of kinetic friction between the box and the ramp?
I have been...
At what depth beneath the surface of a lake is the absolute pressure 6 times the atmospheric pressure of 1.01 x 105 Pa that acts on the lake's surface?
pressure = density * g * h
I thought to multiply 6 * 1.10 X 10^5 pa. Then divide that answer by 1000 kg/m3 (density of water, right?) *...
A uniform solid disk with a mass of 28.3 kg and a radius of 0.414 m is free to rotate about a frictionless axle. Forces of 90.0 N and 125 N are applied to the disk, as the drawing illustrates.

What is the net torque produced by the two forces? (Assume...
do you mean radius = 8.20 / 2 = 4.1
and then 195 * 4.1? I did that and got a wrong answer. I think I am missing something that you are trying to tell me.
Net torque.. so do I have to add those two forces * the radius?
A CD has a mass of 17 g and a radius of 6.0 cm. When inserted into a player, the CD starts from rest and accelerates to an angular velocity of 20 rad/s in 0.65 s. Assuming the CD is a uniform solid disk, determine the net torque acting on it.
I thought to use: torque = I * alpha...
I don't always pick up on little things in problems. In this particular problem, I am unsure of how to draw the picture when the car is rotated.
Here is the problem:
In San Francisco a very simple technique is used to turn around a cable car when it reaches the end of its route. The car...
