Estimate the area between the curve $y = x^2$ and the lines $x = 0$ and $x = 1$, using rectangle method, with four sub intervals. A particle moves a line so that its velocity $v$ at time $t$ is (1) Find the displacement of the particle during the time period $1 \leq t \leq 4$ (2) Find the distance travelled during this time period.

Part 1 (Area estimation): - Curve: $y = x^2$ - Bounds: $x = 0$ to $x = 1$ - Method: rectangle method - Number of sub-intervals: $n = 4$ Part 2 (Particle motion): - Velocity $v$ at time $t$: the explicit velocity function is MISSING from the question (shown only as "(1)"). The time interval
