1. The speed limit on some interstate highways is roughly 100 km/h. (a) What is this in meters per second? (b) How many miles per hour is this? 2. A car is traveling at a speed of 33 m/s. (a) What is its speed in kilometers per hour? (b) Is it exceeding the 90 km/h speed limit? 3. Show that 1.0 m/s = 3.6 km/h. Hint: Show the explicit - steps involved in converting 1.0 m/s = 3.6 km/h. 4. American football is played on a 100-yd-long field, excluding the end zones. How long is the field in meters?
