A 507g mass oscillates with an amplitude of 13.0 cm on a spring whose spring constant is 23.0 N/m. Determine the Period. Determine the maximum speed. Determine the total energy.
A mass of 1.7kg stretches a vertical spring 0.313 m. If the spring is stretched an additional 0.13m and released, how long does it take to reach (new) equilibrium position again.
A top is a toy that is made to spin on its pointed end by pulling on a string wrapped around the body of the top. What is the final angular velocity of the top when the string is completely unwound
Explain how long is the bullet in the target? What average force does the bullet exert on the target? What is the target's speed just after the bullet emerges?

High speed stroboscopic photographs show that the head of a 181 g golf club is traveling at 55.4 m/s, Find the speed of the golf ball just after impact
What are the displacement and velocity of the point on the cord. What is the magnitude of the acceleration of one of the liners toward the other because of their mutual gravitational attraction.
The work done by an external force to move a -7.75 µC charge from point a to point b is 25.0 ? 10-4 J. What is the magnitude of the potential difference between a and b
A u-tube manometer is used to measure the pressure of a vessel under vacuum. Assume the manometer is open to atmospheric pressure (101.325 kPa) and the density of the fluid in the manometer is 12.0 g/cm3. When the vessel is under 11.5 psi of vacuu..
A sailboat is travelling east at 4.0 m/s. A sudden gust of wind gives the boat an acceleration a = (1.35 m/s2 30° north of east). What is the boat's speed 6.0 seconds later while the gust subsides.
A spider of mass m is sitting in a perfectly symmetric web (in a vertical plane with 45 angles between the web lines), where Ti's denote the tensions along the lines that are connected to the spider at the center with i = 1, 2, 3, 4, 5, 6, 7, 8. The ..
An athlete at the gym holds a 1.2 kg steel ball in his hand. His arm is 64 cm long and has a mass of 4.0 kg. Evaluate the magnitude of the torque about his shoulder if he holds his arm straight, but 30 degrees below horizontal?
