Question

The speed v of a particle moving along a straight line, it is at a distance x from a fixed point on the line, is given by $v^2={144}^2-9x^2$ Then

• A. displacement of the particle $\underset{–}{<}$ distance moved by it
• B. the magnitude of acceleration at a distance 3 cm from the fixed point is $27m/s^2$
• C. the motion is simple harmonic with $T=2\pi /3$ sec
• D. the maximum displacement from the fixed point is 4 units

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A displacement of the particle $\underset{–}{<}$ distance moved by it
B the magnitude of acceleration at a distance 3 cm from the fixed point is $27m/s^2$
C the motion is simple harmonic with $T=2\pi /3$ sec
D the maximum displacement from the fixed point is 4 units
