An object's motion can be described by the equation x(t) = (6.0 m/s2)t2-(2.0 m/s)t+1.0 m.
An object's motion can be described by the equation x(t) = (6.0 m/s2)t2-(2.0 m/s)t+1.0 m. a. Find the object's position, velocity, and acceleration at t = 3.0 s. Plot the object's position, velocity, and acceleration (all on separate plots) from t = 0 s to t= 5 s. The following graph shows an object's velocity over time. At t-0 s the objects begins its motion at x = -2m.b. What is the object's displacement from t=0 s to t = 6 s? c....
