The potential energy stored in the compressed spring of a dart gun, with a spring constant of 60.00 N/m, is 1.260 J. Determine by how much is the spring is compressed.
The time required for one complete cycle of a mass oscillating at the end of a spring is 0.25s. what is the frequency of oscillation
A particle is at the position (x,y,z)=(1.0,2.0,3.0)m. It is traveling with a vector velocity (-5.0,+2.8,-3.1)m/s. Its mass is 3.8kg. What is its vector angular momentum about the origin
An object of mass 0.77 kg is initially at rest. When a force acts on it for 2.9 ms it acquires a speed of 16.2 m/s. Find the magnitude of the average force acting on the ball
A simple pendulum is 0.21 m long. Att = 0 it is released from rest starting at an angle of13°.Ignore friction. (Use g = 9.8 m/s2.) What will be the angular position of the pendulum at t = 0.65 s? What will be the angular position of the pendulum at t..

Why three points? Would two have been enough? Describe what changes would occur, if any, in the electric field pattern and in the equipotential curve you measured if the magnitudes of your three charges were increased, all by the same factor.
You are researching personal watercraft (PWC) safety. These vehicles have a well known safety issue in which the rider loses stearing control when there is no thrust from the engine.
