- A car traveling 52.7 km/h is 24.2 m from a barrier when the driver slams on the brakes. The car hits the barrier 1.93 s later. (a) What is the car's constant deceleration magnitude before impact? (b) How fast is the car traveling at impact?1) A man falls from a height of 48 feet. (a) What is the velocity with which he hits the ground? (b) How much time does it take for him to hit the ground?During a hard sneeze, your eyes might shut for 0.38 s.
