In 1967, New Zealander Burt Munro set the world record for an Indian motorcycle, on the Bonneville Salt Flats in Utah, of 295.38 km/h. The one-way course was 8.00 km long. Acceleration rates are often described by the time it takes to reach 96.0 km/h from rest. If this time was 4.00 s and Burt accelerated at this rate until he reached his maximum speed, how long did it take Burt to complete the course?

A person travels by car from one city to another with different constant speeds between pairs of cities. She drives for 60.0 min at 95.0 km/h, 14.0 min at 100.0 km/h, and 60.0 min at 50.0km/h and spends 25.0 min eating lunch and buying gas. (a) Determine the average speed for the trip. (b) Determine the distance between the initial and final cities along the route.

A physics student at a track meet has a radar gun which she can use to measure the speeds of the runners. Shortly after the start of one race she measures that the speed of a runner is 1.57 m/s. When the runner is 11.2 meters farther along the track, she measures the runner’s speed to be 7.87 m/s. Determine the runner’s acceleration during this interval (assuming the runner’s acceleration is constant)?

Usually, Tony travels to Bunbury from Perth city in 2.50 hours. One day he increases his average speed by 12.0 km/h and takes 22.5 minutes less time to reach Bunbury. (a) What was his usual average speed? What was the distance travelled? (b) On the way he stopped at a rail crossing (6.00 m wide) and a train (total length 144m) decelerating at -0.585 ms2 just entered the crossing with a velocity of 13.7 m s¹. Sketch a diagram and find the minimum time for the last carriage of the train to clear the crossing.

A person travels by car from one city to another with different constant speeds between pairs of cities. She drives for 40.0 min at 85.0 km/h, 15.0 min at 100.0 km/h, and 55.0 min at 45.0 km/h and spends 20.0 min eating lunch and buying gas. (a) Determine the average speed for the trip. km/h(b) Determine the distance between the initial and final cities along the route. km

A person on a road trip drives a car at different constant speeds over several legs of the trip. She drives for 15.0 min at 50.0 km/h, 8.0 min at 80.0 km/h, and 30.0 min at 35.0 km/h and spends 25.0 min eating lunch and buying gas. (a) What is the total distance traveled over the entire trip (in km)? km (b) What is the average speed for the entire trip (in km/h)? km/h

A person travels by car from one city to another with different constant speeds between pairs of cities. She drives for 30.0 min at 50.0 km/h, 12.0 min at 60.0 km/h, and 30.0 min at 40.0km/h and spends 55.0 min eating lunch and buying gas. (a) Determine the average speed for the trip.km/h(b) Determine the distance between the initial and final cities along the route. km

You drive a beat-up pickup truck along a straight road for 8.4 km at 70 km/h, at which point the truck runs out of gasoline and stops. Over the next 30 min, you walk another 2.0 km farther along the road to a gasoline station. (a) What is your overall displacement from the beginning of your drive to your arrival at the station?

A motorist has to travel 3.50km in a city where his average speed should not exceed 25km/h. If he increases his average speed 40km/h, how much time will he gain in his journey?
