On the Moon, the acceleration due to the effect of gravity is only about 1/6 of that on Earth. An astronaut whose weight on Earth is 550 N travels to the lunar surface.
(a) What is his weight as measured on the Moon?
N
(b) What is his mass on the Moon?
kg
A 1.83 kg book is placed on a flat desk. Suppose the coefficient of static friction between the book and the desk is 0.542, How much force is needed to keep the book moving at constant speed once it begins moving
You are using a grating with 1000 lines per millimeter; the angle for the first order maxima is ? = 16°. Find the angle for the second order maxima
You are piloting a spacecraft whose total mass is 1170 kg and attempting to dock with a space station in deep space. How long should you sustain the firing of the retro-rocket
Bowling balls can be made from a variety of substances and are required to have a circumference of roughly 27.8 inches. compute the thickness of the shell
A 1.5V battery has an internal resistance of .5 Ohm. If a light bulb with cold resistance of 10 Ohm is placed in a series with the battery, how much current initially flows in the circuit
A cylinder (I = MR^2/2) is rolling along the ground at 7m/s. It comes to a hill and starts going up. Assume no losses to friction, how high does it get before it stops.
A 30.0g ball rolls around the 40.0cm diameter hemishperical track at 60.0rpm. Assume rolling friction is negligible. Determine the ball's linear velocity
