Question

A 5 kg collar is attached to a spring constant 500 N m–1. It slides without friction over a horizontal rod. The collar is displaced from its equilibrium position by 10 cm and released. The maximum acceleration of the collar is

• A. 5 m s–2
• B. 10 m s–2
• C. 15 m s–2
• D. 20 m s–2

Answer 1

Answer: (B)

10 m s–2

Answer 2

Maximum acceleration

$= \frac { 500 \mathrm { Nm } ^ { - 1 } } { 5 \mathrm {~kg} } \times 0.1 \mathrm {~m} = 10 \mathrm {~m} \mathrm {~s} ^ { - 2 }$
