Q. A 13 kg table initially at rest on a horizontal floor requires a 148-N horizontal force to set it in motion. Once the table is in motion, a 98-N horizontal force keeps it moving at a steady velocity. What is the coefficient of kinetic friction between the table and floor?
how long does it take the boat to make a round trip consisting.
A capacitor (capacitance C1) is connected across the terminals of an ac generator. Without changing the voltage or frequency of the generator, a second capacitor (capacitance C2) is added in series with the first one.
An airplane is flying with a velocity of 93.0 m/s at an angle of 22.0^circ above the horizontal. When the plane is a distance 119 m directly above a dog that is standing on level ground, a suitcase drops out of the luggage compartment.
A plate carries a charge of -3.9 µC, while a rod carries a charge of +2.2 µC. How many electrons should be transferred from the plate to the rod, so that both objects have the same charge.
The bunchberry flower has the fastest-moving parts ever seen in a plant.at first , the stamen are held by the petals in a bent position, storing elastic energy like a coiled spring.
A parallel-plate air capacitor with a capacitance of 245 has the charge of magnitude 0.1502 on each plate. The plates have the separation of 0.323.
A spring of k=12.00 N/m has a block of mass 11- kg attached to it on a frictionless table. If the block is pulled a distance 0.17m to the right and released from rest, how long would it take the block to return to its equilibrium position? Give yo..

A sports car moving at constant speed travels 90 m in 4.9s. If it then brakes and comes to a stop in 4s, what is its acceleration? Express the answer in terms of g's, where g = 9.80 m/s2. (Take the positive direction to be direction of travel.)
The immediate environment of a reactor contains a large flux of 10 MeV gamma rays. Resolve the thickness of lead required to reduce the intensity by a factor of 1012. Assume the mass absorption coefficient of Pb for 10 MeV photons is m/r = 0.06 cm..
What is the speed of the projectile immediately before it hits the ground if air friction does one and a half times as much work on the projectile when it is going down as it did when it was going up.
The 3.3 kg piece of wood slides on the surface. The curved sides are perfectly smooth, but the rough horizontal bottom is 35 m long and has the kinetic friction coefficient of 0.24 with the wood. The piece of wood starts from rest 6.0 m above the rou..
