A car is travelling with varying speed, and at the moment t = 0 the speed is [30 marks] 100 km/h. The car gradually slows down according to the formula - L(t) = at — bt2, t≥ 0, where L(t) is the distance travelled along the road and b = 90 km/h2. The value of a is not given, but you can find it. Using derivative, find the time moment when the car speed becomes 10 km/h. Find the acceleration of the car at that moment.

The y-coordinate of a particle in curvilinear motion is given by y = 12.6t³-13.8t, where y is in inches and t is in seconds. Also, the particle has an acceleration in the x-direction given by a = 9.1t in./sec².
