2) A car going down the road has a velocity of 20 m/s. If the car continues at this rate for 7 seconds how far did the car go?

Does the distance travelled by an oscillating mass between times t=0 and t2 equal the displacement of the particle over the same time period if t2> t/2? hint: consider a sine wave starting at t1=0, then consider a closing wave starting at t1=0, for your explanation.
