Two bicyclists were riding their bikes at a rate of 20 kilometers per hour (km/h). During the next half hour, they observed that they had increased their speed to 26 km/h. What was their average acceleration?

A student drives the 105-mi trip back to campus after spring break and travels with an average speed of 63 mi/h for 1 hour and 30 minutes for the first part of the trip. (a) What distance was traveled during this time? Answer: 94.5 mi (b) Traffic gets heavier, and the last part of the trip takes another half-hour. What was the average speed during this leg of the trip?   (c) Find the average speed for the total trip.

A ball rolls along flat ground at 7.5 m/s (call this the positive direction) then encounters a hill. If the ball rolls 19 m up the hill before coming to a stop, what was the acceleration (in m/s2) experienced by the ball as it rolled up the hill?
