Find the final velocity of the driver when she reaches the finish line. Define functions x(t), y(t), so that at time t (in seconds) Lindsay's position on the coordinate plane is given by (x(t), y(t)). Acceleration is the rate at which the velocity of a body changes with time. Calculus allows us to see the connection between these equations. This activity helps students better understand the relations between position, velocity, acceleration, and when an object is speeding up or slowing down. In any case, Path. At the lowest point (trough) of the cycle, the DUT is again momentarily at a standstill and the velocity is zero. Note that this uses the Sketch feature and so is ideally suited to a tablet, though . When the acceleration is constant (positive), and the initial velocity of the particle is zero, the velocity of the particle will increase linearly as predicted by the equation: v = u + at Since u = 0 v = at As shown in the figure, the velocity of the particle will increase linearly with respect to time.
