Consider two wheels with fixed hubs. The hub cannot move, but the wheel can rotate about it. The hubs are fixed to a stationary object. The hubs and spokes are mass-less, so that the moment of inertia...

Q1: a test pilot whose mass is 85 kg is strapped into a large centrifuge machine for training. The machine spins rapidly to stimulate increased gravitational forces on the body. If the machine spins...

Q1: What is the gravitational force between two 200 g masses that are 65 cm apart? Q2: A child's baton is 0.50 m long, and each end has a mass of 0.15 kg. What is the moment of inertia...

A 2.10-mole sample of an ideal gas is allowed to expand at a constant temperature of 278 K. The initial volume is 14.5 L and the gas performs 945 J of work. What is the final volume of the container...

Michelle swings a 0.009-kg rubber stopper around her head. The rubber stopper is tied to a string that Michelle holds at 0.72 m while swinging it once every 0.5s. What is the minimum force she needs...

a hiker throws a ball horizontally from a hill 21.0 m high. The hiker's height is 1.750 m. The magnitude of the horizontal velocity is 7.0 m/s. Find the distance between the base of the hill and the...

The moon has an average radius of 1.74x10^6 m. A 68.kg person on the moon's surface weighs only 110 N. What is the mass of the moon?

Q: what type of force is gravity? Q: Two marbles are rolling horizontally on a table. The red marble travels at 1.22 m/s, while the blue marble travels at 1.67 m/s. If both roll off the table at the...

Michelle swings a 0.009-kg rubber stopper around her head. The rubber stopper is tied to a string that Michelle holds at 0.72 m with a force of 21. N. If she lets go of the string, what is the...

Question 1 A Geiger counter gets 8000 counts per minute from a certain source with a half-life of 5 years. How many years until its activity is 1000 counts per minute? Question 2 The...

I am not sure what equation to use to solve this. I understand this is fairly simple, but just want to make sure I am doing it right.

A 2.95-kg object is moving in a plane, with its x and y coordinates given by x = 3t2 − 2 and y = 4t3 + 3, where x and y are in meters and t is in seconds. Find the magnitude of the net force acting...

A pole-vaulter of mass 75 kg reaches a maximum speed of 7 m/s just before he jams his pole into the notch to launch himself over the bar. Assuming that his pole is only 80% efficient, what is the...

Light with a frequency of 6.1*10^14 Hz is measured from a star. This type of star is known to produce light with a frequency of 6.0*10^14 Hz. How fast is the star moving away from toward Earth?
