Find the average force exerted on the bullet
A 12 g bullet is accelerated in a rifle barrel 48.3 cm long to a speed of 736 m/s. Use the work-energy theorem to find the average force exerted on the bullet while it is being accelerated.

A parallel-plate capacitor has an area of 5.15 cm2, and the plates are separated by 1.05 mm with air between them. It stores a charge of 337 pC. What is the potential difference across the plates of the capacitor?
25g ball moving at velocity of 200cm/s to the right collides and stick to 200g block that is intially at rest and is attached to spring of spring constant at 10n/m. Find max compression of spring.
After the first spring compresses a distance of 27.3 cm, the second spring acts with the first to increase the force as additional compression occurs as shown in the graph. The car comes to rest 49.5 cm after first contacting the two-spring system
This implies that you can pick the point about which to sum the torques to simplify the calculation. Often it is best to pick the point where an unknown force acts, so that the torque due to that force is zero. In this problem the simplest equati
A space station is constructed in the shape of a wheel 15 m in diameter, with essentially all of its 4.0×105 kg mass at the rim. Once the station is completed, it is set rotating at a rate that requires an object at the rim to have radial ac
