Question: 1 a 75kg mass attached to a spring with a...

Question details

1) A 7.5kg mass attached to a spring with a spring constant of 365 N/m oscillates on a horizontal, frictionless track. Att 0, the mass is released from rest at x-2.32 cm. (That is, the spring is stretched by 2.32 cm.) (a) Determine the frequency of the oscillations. (b) Determine the maximum speed of the mass. Where does the maximum speed occur? (c) Determine the maximum acceleration of the mass. Where does the maximum acceleration occur? 2) A body is vibrating with simple harmonic motion of amplitude 14cm and a frequency of 10.2 Hz What is its maximum acceleration and maximum velocity? V, a . What is its acceleration and velocity for a displacement of 5cm? The motion starts 14cm from the equilibrium. 4) Two point charges of +3uC and -6uC are separated by a distance of 12 cm. A +7uC charge is placed midway between these two charges. What is the electric force acting on the +3uC charge? 3) Two equal charges (Q +285 HC) are situated at the diagonal corners A and C of a square of side 10 cm. What is the magnitude of the electric field at point B? small object with a charge of -9 uC is placed at point B. What force acts on the object? A
