Question

The position of an object as a function of time is given by x = At2 – Bt + C, where A = 7.3 m/s2, B = 5.8 m/s, and C = 4.5 m. Find the instantaneous velocity and acceleration as functions of time. (Use the following as necessary: t.)

help!!!!!!!!! thank you!!

Answer 1

v=dx/dt=2At-B
a=dv/dt=2A
