Hooke's law, law of elasticity discovered by the English scientist Robert Hooke in 1660, which states that, for relatively small deformations of an object, the displacement or size of the deformation is directly proportional to the deforming force or load.

To find the percentage error in the measurement of velocity, we first need to calculate the velocity using the given displacement and time. Given: Displacement = 400 + 10 = 410 meters Time = 40 + 0.4 = 40.4 seconds Velocity = Displacement / Time = 410 meters / 40.4 seconds ≈ 10.1386 meters per second Now, we can calculate the percentage error in the measurement of velocity. To do this, we need to consider the errors in both displacement and time. Let's assume the errors in displacement and time are Δd and Δt respectively. Then: Percentage error in velocity = [(Δd/d) + (Δt/t)] * 100% Given: Δd = 10 meters (since the error in displacement is 10 meters) Δt = 0.4 seconds (since the error in time is 0.4 seconds) Percentage error in velocity = [(10/410) + (0.4/40.4)] * 100% ≈ [(0.0244) + (0.0099)] * 100% ≈ 0.0343 * 100% ≈ 3.43% So, the percentage error in the measurement of velocity is approximately 3.43%.
