can you please do (d) and (e)? 

Problem 2: A car moves on a straight road such that its position from a reference point is given by the following function: { x(t) = 3 + 5t + 2t² + 0.4t³, y(t) = 0, z(t) = 0 } where t is in seconds and x in meters. Part (a) True or False: the acceleration of the car is constant? MultipleChoice : 1) True 2) False Part (b) Find the acceleration, in meters per square second, in the x-direction at t = 0.95 sec. Numeric : A numeric value is expected and not an expression. a(t1) = Part (c) Find the acceleration, in meters per square second, in the x-direction at t = 1.5 sec. Numeric : A numeric value is expected and not an expression. a(t2) = Part (d) Find the average velocity, in meters per second, in the x-direction between t1 = 0.95 s and t2 = 1.5 s. Numeric : A numeric value is expected and not an expression. Vave = Part (e) Find the average acceleration, in meters per second squared, in the x-direction between t = 0.95 s and t2 = 1.5 s.
