CAPE Physics Unit 1 · 2012 · Paper 2 · Question 1(b)(iii)

Figure 1 shows data for the displacement, x, of a particle at various times, t. The displacement is described by the equation x = x₀(t/t₀)ⁿ, where x₀ and t₀ are constants.

Given that t₀ = 5 s, determine the velocity of the particle when t = 30 s.
