If one object has a greater speed than a second object, does the first necessarily have a greater acceleration? Explain, using examples.
A rope is wrapped around a wheel of radius R=2.0 meters. The wheel is mounted with frictionless bearings on an axle through its center. What is the moment of inertia of the wheel
The 20-cm-long wrench in the figure swings on its hook with a period of 0.80s, What is the moment of inertia about the hook
Consider Fig. The bottom histogram appears "best" with respect to being completely within specification limits and reasonably mound shaped.
Suppose a cart was given a push down a ramp, starting at the end close to the motion detector, Describe what the acceleration vs. time graph will look like for this case, Explain why the two graphs would be the same or different
A light rod 1.00 meter in length rotates about an axis perpendicular to its length and passing through its center. Compute what is the system kinetic energy when its angular speed is 2.50 rad/s
Two round concentric metal wires lie on a tabletop, one inside the other. The inner wire has a diameter of 18.0cm and carries a clockwise current of 14.0 A, as viewed from above, and the outer wire has a diameter of 38.0 cm.
The drawing shows two positive charges q1 and q2 fixed to a circle. At the center of the circle they produce a net electric field that is directed upward along the vertical axis. Decide the ratio q2/q1.
A 2.20- bullet embeds itself in a 1.60- block, which is attached to a spring of force constant 780. Find the time for the bullet-block system to come to rest
A 1.50 kg block rests on the icy surface of a frozen pond, which you can suppose to be friction less. If the location of the block is measured to a precision of0.20 cm, what is the minimum certainty in the block's speed, assuming the mass is known ex..
