A 12-Kg Block on a Horizontal Frictionless Surface Is Attached

question 32

Multiple Choice

A 12-kg block on a horizontal frictionless surface is attached to a light spring (force constant = 0.80 kN/m) .The block is initially at rest at its equilibrium position when a force (magnitude P = 80 N) acting parallel to the surface is applied to the block,as shown.What is the speed of the block when it is 13 cm from its equilibrium position?

• A)0.78 m/s
• B)0.81 m/s
• C)0.71 m/s
• D)0.58 m/s
• E)0.64 m/s

Definitions:

Capacitor Circuit

A circuit that includes a capacitor, which stores electrical energy in an electric field, affecting the current and voltage relationship in the circuit.

Capacitive Reactance

The measure of opposition that a capacitor presents to alternating current, depending on the frequency of the current and the capacitance value.

Capacitive Reactance

A measure of opposition that a capacitor offers to alternating current (AC), dependent on the frequency of the current and the capacitor's capacitance.

Applied Frequency

The frequency, typically measured in hertz (Hz), at which an alternating current (AC) is supplied to a circuit or device.
