Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.

Question

Two masses are connected by a light string that passes over a frictionless pulley, as shown below. The masses are m1 = 6.32 kg, and m2 = 7.51 kg. If the coefficient of friction between the incline and m2 is 0.232 and the angle of the incline is 35.0°, find (a) acceleration of the two masses, (b) the tension in the string, and (c) the speed of each mass 2.11 s after being released from rest. (d) Also, determine what m2 would have to be in order to have the system accelerate in the direction opposite of what you found in (a). Assume m1 stays at the same. Note: this problem needs to be done using forces and FBDs - no credit will be given for doing it any other way.
In this example we will add friction to an inclined ramp. Of course, friction does work and we will need to determine its contribution to WotherWother. A crate full of machine parts sits on the floor; the total mass is 8.0 kg. The crate must be raised to the floor of a truck by sliding it up a ramp 2.5 m long, inclined at 30∘. The shop foreman, giving no thought to the force of friction, calculates that he can get the crate up the ramp by giving it an initial speed of 5.0 m/S at the bottom and letting it go. Unfortunately, friction is not negligible; the crate slides 1.6 mm up the ramp, stops, and slides back down. (Figure 1) shows the situation. (a) Assuming that the friction force acting on the crate is constant, find its magnitude. (b) How fast is the crate moving when it reaches the bottom of the ramp? PART B Suppose the foreman had released the box from rest at a height of 0.25 m above the ground. What would the crate's speed be when it reaches the bottom of the ramp?
