A 20.0 uF capacitor is charged with a 150.0 V power supply, then disconnected from the power and connected in series with 0.280 m Inductor. Compute: (a) the oscillation frequency of the circuit :(b) the energy stored in the capacitor at time t=0 ms(the moment of connection with the inductor); (c) the energy stored in the inductor at t=1.30 ms.
A two-stage rocket moves in space at a constant velocity of 4700 m/s. Find what is the velocity (magnitude and direction) of the 2500 kg lower stage after the explosion
An automobile moves at constant speed down one hill and up another hill along a smoothly curved surface. What will the diagrams for the directions of the velocity and the acceleration of the automobile at the instant that it is at the lowest position..
A 20 g ball is fired horizontally with initial speed v_0 toward a 110 g ball that is hanging motionless from a 1.10 m-long string. The balls undergo a head-on, perfectly elastic collision, after which the 110 g ball swings out to a maximum angle t..
