What is coefficient of kinetic friction between sled
What is coefficient of kinetic friction between sled
Physics
A sled is pulled with a horizontal force of 20 N along a level trail, and the
acceleration is found to be 0.35 m/s2. An extra mass m = 4.2 kg is placed on the
sled. If the same force is just barely able to keep the sled moving, what is the
coefficient of kinetic friction between the sled and the trail?

A rear wheel on a Formula 1 racing car has a mass of 3.2 kg and a radius of 0.42m.
A mechanic is rolling the wheel towards a step at the back of the workshop. Decide:
1. The minimum horizontal force (F) needed to be applied through the axle (center)
of the wheel to just start rolling over the step if it is 6cm tall.
2. The minimum horizontal force required to be applied at the top of the wheel to
just start it rolling over the same step.

distance L, estimate what is its kinetic energy and speed.
How much energy is stored in the capacitor in picojoules
How much energy is stored in the capacitor in picojoules
Physics
A cylindrical capacitor is 0.047 m long and has a cylindrical core with a radius of
0.025 mm and a cylindrical metal sheath with a radius of 0.084 mm. The space
between the core and the sheath is filled with a dielectric with a dielectric
constant of [k]. If a battery provides a potential difference of 12 V to this
capacitor, how much energy is stored in the capacitor in picojoules (pJ)?

Gravitational force exerted on the point mass with the rod
Physics
Compute the gravitational potential due to a thin rod of length L and mass M at a
distance R from the center of the rod and in a direction perpendicular to the rod.
Secondly, consider a point mass located at a distance D from the nearest end of a
thin rod of length L and mass M along the axis of the rod. Discover the
gravitational force exerted on the point mass with the rod.
