The acceleration of a particle is given by a = 2t-20, where a is in meters per second squared and t is in seconds. Determine the velocity
and displacement as functions of time. The initial displacement at t = 0 is so = -5 m, and the initial velocity is vo = 6 m/s. Once you have
determined the functions of time, answer the questions.

An airplane covers a straight-line distance of 8.59 km in 30 .1 s, during which time it has a constant forward acceleration of 3.68 m/s2. What is the speed of the airplane, in m/s, at the beginning of the 30.1 s?
A human-powered vehicle (HPV) team wants to model the acceleration during the 260-m sprint race (the first 60 m is called a
flying start) using a = A – Cv, where a is acceleration in m/s2? and v is the velocity in m/s. From wind tunnel testing, they found
that C = 0.0012 m-1. Knowing that the cyclist starts from rest and is going 110 km/h at the 260-meter mark, what is the value of
A?
