20t - + 6t + 5 represents the distance, x meters, moved

20t - + 6t + 5 represents the distance, x meters, moved by a body in t 23t2 seconds. Determine (a) the velocity and acceleration at the start, (b) the velocity and acceleration when t=3s. (c) the values of t when the body is at rest. (d) the value of t when the acceleration is 37m/s?, and (e) the distance travelled in the third second.
