Q. An air-track glider attached to a spring oscillates between the 10.0 {rm cm} mark and the 58.0 {rm cm} mark on the track. The glider completes 15.0 oscillations in 35.0 {rm s}. What are the (a) period, (b) frequency, (c) amplitude, and (d) highest speed of the glider?
In a physics lab, a cube slides down a frictionless incline and elastically strikes another cube at the bottom that is only 1/4 its mass. If the incline is 35 high and the table is 95 off the floor, where does each cube land.
An extension cord made of two wires of diameter 0.129 {rm cm} (no. 16 copper wire) and of length 1.5 m (5 ft) is connected to an electric heater which draws 13.5 A on a 120-{rm V} line. How much power is dissipated in the cord.

What is frequency of the fork
Why is you are not harmed with the contact of a charged metal ball, although its voltage may be very high? Is the reason similar to why you are not harmed by greater-than-10000 C sparks from the Fourth-of-July sparkler? Define your answer in terms..
An electron moves at right angles to a magnetic field of 0.109 T. What is its speed if the force exerted on it is 9×10-15 N.
A 33.2 m steel wire and a 25.6 m copper wire both with 1.00 mm diameters, are connected end to end and are stretched to a tension of 120 N. How long does it take the transverse wave to travel the entire length of the two wires.
At one instant a bicyclist is 25m due east of a park's flagpole, going due south with a speed of 8 m/s. Then, 11 s later, the cyclist is 65m due north of flagpole, going due east with a speed of 10 m/s.
find magnitudes of the tension forces in the first two ropes. what is the velocity of the cart when it reaches its greatest y coordinate.
Two charged bodies exert a force of .145N on each other. If they are now moved so they are one fourth as far apart, what force is exerted.
A box of mass 32 kg is at rest on a horizontal frictionless surface. A constant horizontal force then acts on the box, and accelerates it to the right. It is observed that it takes the box 6.5 seconds to travel 48 meters. What is the magnitude of for..
An airplane is flying with a velocity of 90 at an angle of 22 above the horizontal. When the plane is a distance 122 directly above a dog that is standing on level ground, a suitcase drops out of the luggage compartment.
