Mathematics 1 Deneme Sınavı Sorusu #1357103

A car moves along a road in such a way that its position at time t is f(t) = t³ + t² + t (metre). What is the velocity of the car at the instant t=2 equal to?

Yanıt Açıklaması:

In order to find the instantenous velocity the derivative of the function must be taken. This is equal to 3t² + 2t + 1. The velocity at this instant is equal to the value found when t=2 is plugged in: (3*2²)+ (2*2) + 1 = 12 + 4 + 1= 17(metre/seconds). The answer is B.
