The function s(t)=ť - 12t - 9 gives the distance from a starting point at time t of a particle moving along a line. Find the velocity and acceleration functions. Then find the velocity and acceleration at t= 0 and t=3. Assume that time is measured in seconds and distance is measured in centimeters. Velocity will be in centimeters per second (cm/sec) and acceleration in centimeters per second per second (cm/sec2). The velocity function is v(t) = (Simplify your answer.)
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....
