Final answer:

For a mass-spring system undergoing simple harmonic motion with a given mass of 10 g and spring constant of 10 N/m, the next time the mass will be at maximum displacement is approximately 0.3 seconds. Option d is the answer.

Step-by-step explanation:

The question concerns the next time the mass will be at maximum displacement when dealing with simple harmonic motion (SHM) of a mass attached to a spring. The period of oscillation 'T' for a mass-spring system in SHM can be calculated using the formula:

T = 2π √(m/k)

where:

  • m is the mass in kilograms (kg),
  • k is the spring constant in newtons per meter (N/m).

Given that the mass is 10 g (0.01 kg) and the spring constant is 10 N/m, the period 'T' is:

T = 2π √(0.01 kg / 10 N/m)

T = 2π √(0.001)

T = 2π √(1/1000)

T = 2π / 10

T = 0.2π

Approximating π to 3.14:

T = 0.2 × 3.14 ≈ 0.628 seconds

The mass will thus be at maximum displacement again after half a period, as that is the time it takes to go from one extreme to the other extreme in SHM:

Next maximum displacement = T/2

Next maximum displacement = 0.628 / 2 ≈ 0.314 seconds

The closest answer in the provided options, accounting for rounding, would be:

d. 0.3 seconds
