Question

An object starts from rest and accelerates 4.3 m/s^2 for 2.05 seconds. What is its displacement from the start position

Answer 1

displacement = s = v1t +1/2at2
                            = 0 * 2.05 +1/2*(4.3)*(2.05^2)
                            = 0 + 9.04 
                            = 9.04 m
