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.

A particle’s velocity along the x-axis is described byv(t) = A t + B t2,where t is in seconds, v is in meters per second, A = 1.14 m/s2, and B = -0.56 m/s3.
What is the acceleration, in meters per second squared, of the particle at time t0 = 1.0 s?
What is the displacement, in meters, of the particle between times t0 = 1.0 s and t1 = 3.0 s?
What is the distance traveled, in meters, by the particle between times t0 = 1.0 s and t1 = 3.0 s?
The velocity of a particle is given by v = 23t2 - 110t + 52, where v is in meters per second and t is in seconds. Plot the velocity v and
acceleration a versus time for the first 6.4 seconds of motion and evaluate the velocity when a is zero. Make the plots and then
