A 150-? resistor is connected in series with a 0.250-H inductor. The voltage across the resistor is vR=(3.80V)cos[(720rad/s)t]. Derive an expression for the circuit current
Suppose a 65 kg person stands at the edge of a 6.5 m diameter merry-go-round turntable that is mounted on frictionless bearings and has a moment of inertia of 1850 kg m2. Calculate the angular velocity of the turntable
Giancoli, page 30 --when they say that x-xo increases with the square of the initial speed. Why do they say square of initial speed only, what about square of final speed? And why do they ignore that the distance also decreases by a factor of 2.
A teeter-totter is made of a 5.400 m long plank with a mass of 58.0 kg, with a fulcrum (pivot point) located 2.900 m from the right end. If a box with a mass of 94.0 kg is placed at the extreme right end of the plank, what mass must be placed at the ..
