A physicist at a fireworks display times the lag between seeing an explosion and hearing its sound, and finds it to be 0.400 s. (a) How far is the explosion if air temperature is 24.0 °C and if you neglect the time taken for light to reach the physicist? (b) Calculate the distance to the explosion taking the speed of light into account. Note that this distance is negligibly greater.

A skier starts at the top of a 12º frictionless slope with a speed of 2.5 m/s. Her speed at the bottom is 15 m/s. Part A What is her acceleration on the slope? Part B What is the length of the slope? Part C How long does it take her to reach the bottom?
A car travelling at the speed Vo on a straight level road. After the brakes are applied at t = 0, the motion can be approximated by s = t^3/100− t^2 + 17t where s is thedistance traveled in meters and t is the time in seconds. a. gives the value of Vo b. gives the distance required for the car to stop.
