Landing with a speed of 78.3 m/s, and traveling due south, a jet comes to rest in 959 m. Assuming the jet slows with constant acceleration, find the magnitude and direction of its acceleration.

Turning a doorknob through 0.53 of a revolution requires 0.10 J of work. What is the torque required to turn the doorknob?

A person with perfect pitch sits on a bus bench listening to the 444 Hz horn of an approaching car. If the person detects a frequency of 480 Hz, how fast is the car moving?

Suppose the charge q2 in the figure below can be moved left or right along the line connecting the charges q1 and q3. Given that q = +15 µC, find the distance from q1 where q2 experiences a net electrostatic force of zero? (The charges q1 and q3 are separ...

Suppose the charge q2 can be moved left or right along a line connecting charges q1 and q3. Given that q = +15 µC, find the distance from q1 where q2 experiences a net electrostatic force of zero? (The charges q1 and q3 are separated by a fixed distance o...

A 20.0 mL sample of gastric juice was taken from a patient suspected of having hypochloridia (low stomach acid). The sample was taken several hours after a meal so there was no ingested food or drink, and it was assumed no buffers were present. The sample...

Two small plastic balls hang from threads of negligible mass. Each ball has a mass of 0.14g and a charge of magnitude q. the balls are attracted to each other. When in equilibrium, the balls are separated by a distance of 2.05cm and the threads attached t...
