Problem: You are riding in an elevator on the way to the eighteenth floor of your dormitory. Near the end of your upward trip, while the elevator is going up and slowing down, the magnitude of the elevator's acceleration is a = 1.87m/s^2. Beside you is the box containing your new computer; box and contents have a total mass of 28.0kg. While the elevator has the described acceleration, you push horizontally on the box to slide it at constant speed toward the elevator door.
Part A: If the coefficient of kinetic friction between the box and elevator floor is µk = 0.32, what magnitude of force must you apply?
I need help to determine what magnitude of force you apply.
Two spherical objects have a combined mass of 200. The gravitational attraction between them is 8.01×10-6 while their centers are 21.0 apart.
A body slides down a plane inclined at 40 degrees to the horizontal, with an acceleration of 2.3 meters/second^2. Determine the coefficient of kinetic friction
A boy ties a small stone to one end of a string and holding the other end, he whirls the stone above his head in a horizontal circle. If the stone has a mass of 0.5 kg, find the centripetal force on the stone

A circuit consists of a 259- resistor and a 0.260-H inductor. Determine the phase angle between the current and the voltage of the generator. Note: The ac current and voltage are rms values and power is an average value unless indicated otherwise
The ink drops have a mass = 1.0×10-11 each and leave the nozzle and travel horizontally toward the paper at velocity = 22. The drops pass through a charging unit that gives each drop a positive charge by causing it to lose some electrons.
A gas is allowed to expand at a constant pressure of 10^7 Pa, its volume increasing by 2m^3. What is the net work done by the gas during the entire process
Use the unit factor method to solve the following problems. Set up each problem in the exact same way (using all six steps). Show all your work. Apples sell for 43 cents a pound. How much do 3.2 pounds of apples cost? Gold costs $500 per ounce. A sol..

Three charges (q1 = 7.6 ?C, q2 = -4.7 ?C, and q3 = 1.1?C) are located at the vertices of an equilateral triangle with side d = 6.1 cm. q1 is on the bottom left, q2 is on the bottom right, and q3 is at the top.
A binary system consists of two stars that revolve in a circular orbit about a center of mass midway between them. This means that the masses of two stars are equal. Suppose the orbital speed of each star is 285 km/s and the orbital period of each..
