Question

the distance x metres described by a car in time t sec is x=3t³-2t²+4t-1. determine the velocity and acceleration when t = 0 s and t = 1.5 s​

Answer 1

Answer:

velocity at 0 s is 4 units and at 1.5 s is 18.25 units .

acceleration at 0 s is -4 units (i.e., deceleration) and at 1.5 s is 23 units
