A particle whose mass is 2.3 kg moves in the xy plane with velocity = (3.8 m/s)î along the line y = 4.8 m.
(a) Find the angular momentum about the origin when the particle is at (12 m, 4.8 m).
Magnitude = kg · m2/s
(b) A force = (-4.3 N)î is applied to the particle. Find the torque about the origin due to this force as the particle passes through the point (12 m, 4.8 m).
Magnitude = N · m
A charge of -2.05 nC and a charge of -6.20 nC are separated by a distance of 70.0 cm. Find the position at which a third charge of +7.20 nC can be positioned ( from the -2.05 nC charge) so that net electrostatic force on it is zero.
A uniform chain with a mass of 1.38 kg per meter of length is coiled on a table. One end is pulled upward at a constant rate of 0.54 m/s. how much force must be applied to the end being raised

A sample contains radioactive atoms of two types, A and B. Initially there are three times as many A atoms as there are B atoms. Two hours later, the numbers of the two atoms are equal. The half-life of A is 0.72 hours. What is the half-life of B?
The fuel tank on a car is d = 0.35 m tall. The fuel level in the tank is detected by a L = 0.66 m arm that is free to rotate about a pivot at an upper fuel tank corner. Its sensor end floats at the surface of the fuel as indicated in the diagram, ..
