A 1.00-kg glider attached to a spring with a force constant of 25.0 N/m oscillates on a horizontal, frictionless air track. At t = 0 the glider is released from rest at x = -3.00 cm. (That is, the spring is compressed by 3.00 cm.) Find (a) the period of its motion, (b) the maximum values of its speed and acceleration, and (c) the position, velocity, and acceleration as functions of time.
Two small insulating spheres with radius 9×10-2 are separated by a large center-to-center distance of 0.52. One sphere is negatively charged.
For many years Colonel John P. Stapp, USAF, held the world's land speed record. He participated in studying whether a jet pilot could survive emergency ejection.
You're standing on a carousel 1.34 m from its axis of rotation. What minimum distance would you need to walk to arrive at a position where your contribution to the total moment of inertia has doubled?
A 2.00-g charged particle is released from rest in a region that has a uniform electric field = (160 N/C) . After traveling a distance of 0.520 m in this region, the particle has a kinetic energy 0.080 J. Determine the charge of the particle.
what is the maximum speed the ball can have. imagine there are no other forces acting on the particle.
What is the charge on each sphere if the two charges are alike?
A square plate of copper with 47.0 cm sides has no net charge and is placed in a region of uniform electric field of 79.0 kN/C directed perpendicularly to the plate. (a) Find the charge density of each face of the plate. (b) Find the total charge ..
Two trains and a bird Two trains, each having a speed of 23km/h, are headed at each other on the equal straight track. A bird that can fly 60km/h flies off the front of one train when they are 70 km apart and heads directly for the other train.
Assuming that the bond energy holding together a water molecule is typical, use table below to estimate how various molecular bonds might be broken with this energy.
When blue light of wavelength 465 nm illuminates a diffraction grating, it produces a 1st order utmost but no 2nd order maximum.
