1. A sport car starting from rest can attain a speed of 60 mi/hr in 8s. A runner can do a 100-yd dash in 9.8s. Assume that the runner is moving with a constant speed and that the car starts at the instant he passes it. How far will both travel until the car overtakes the runner? (convert distances to ft, time to s) 2. An automobile traveling 56 km/hr is 24m from a barrier when the driver slams on the brakes. The car hits the barrier two seconds later. (a) What was the car's deceleration before the impact? (b) How fast was the car traveling at impact? (distances to m, time to s) Help?
