Document Summary

If object a can run at a speed of 110km/h. The best an object b can do is a speed of. Object b and object a are initially 0. 400km apart. A and object b are running at their top speed, how long does object a to takeover. Step 1: draw a position-time diagram to show the position of object a and object b. x. We use the formula : xfinal = xinitial + velocity x time. Step 3: use given information and correct formula to set equation. xfinal of object a = xfinal of object b => 110t = 0. 4 +35t => t=5. 33 x 10-3 h = 19. 2 s: free falling. Note: all objects fall with the same acceleration, no matter an apple or a piece of feather. All objects fall with the same acceleration at 9. 8m/s2 (notated as = )
