I think im doing them right but they dont match the answers that were supplied to me - i think the answers may have typos. 1. A bike accelerates uniformly from rest to a speed of 7.10 m/s over a distance of 35.4 m. Determine the acceleration of the bike. my answer: I used the formula v^2 = vo^2 + 2ad and got a = .712 m/s^2 2. A car traveling at 22.4 m/s skids to a stop in 2.55 s. Determine the skidding distance of the car (assume uniform acceleration). my answer: I solved for acceleration first (-8.78 m/s^2) then used d=Vot + 1/2(a)t^2 to get d = 28.57 m. 3. A bullet is moving at a speed of 367 m/s when it embeds into a lump of moist clay. The bullet penetrates for a distance of 0.0621 m. Determine the deceleration of the bullet when moving into the clay. my answer: I used the formula v^2 = vo^2 + 2ad and got a = -1.08 x 10^6 m/s. (my issue here is that the answer should be negative, not positive. right?) 4. A dragster accelerates to a speed of 112 m/s over a distance of 398 m. Determine the acceleration of the dragster. my answer: Once again I used the formula v^2 = vo^2 + 2ad (with Vo = 0; at least I assume that is true) and got a = 15.76 m/s^2. I think my equations and answers are right but if not, can someone help me out and correct me where I have made mistakes. Thanks.
