If you had an experimental set-up, where a wire with a linear mass density of 1 g/m was clamped at one end and passed over a pulley located 200 centimeters from the clamp with a mass of 3.0 kg hung directly from the end of the wire and you wished to produce a standing wave pattern having 1 nodes, at what frequency would you need to vibrate the wire?
A 1500 {rm kg} car skids to the halt on a wet road where mu_k = 0.50. How fast was the car travelling if it leaves 66-{rm m}-long skid marks.
A m = 1.30-kg block is pushed against a spring with negligible mass and force constant k = 580 N/m, How far does the object travel up the incline before starting to slide back down
An ion accelerated through a potential difference of 102 V experiences an increase in kinetic energy of 3.01 × 10?17 J
A 1110 N uniform beam is attached to a vertical wall at one end and is supported by a cable at the other end. A 1960 N crate hangs from far end of beam.
An observer, whose eyes are 1.77 m above the ground, is standing 28.0 m away from a tree. The ground is level, and the tree is growing perpendicular to it. The observer's line of sight with treetop makes an angle of 22.0° above the horizontal. How..
How fast is the shadow of the plane moving along the ground? (That is, what is the magnitude of the horizontal component of the plane's velocity?)
You are in a hot-air balloon that, relative to the ground, has a velocity of 4.65 m/s in a direction due east. find direction of the hawk's velocity relative to the ground
You are pulling a crate across the floor. The block has a mass of 65.0 kg. You exert a horizontal force of 140. find direction of the acceleration of the crate
If the blocks move determine the magnitude of their acceleration. If the blocks move determine the magnitude of the tension in the string. If the blocks do not move evaluate the sum of the magnitude of the forces of friction acting on the blocks...
An 880 N box is pushed across a level floor for a distance of 5.0m with a force of 440N. How much work was done on the box
