A group of friends are going on a day out to Dhaka Resort. They divided their route into 3 equal parts, and planned on maintaining an average speed of 59 km/h on their way to their destination. Their speed for the first and second part were 65 km/h and 84 km/h respectively. What speed should they maintain for the third part of their journey if they are to achieve their target average speed?

Cheetahs can accelerate to a speed of 20.0 m/s in 2.50 s and can continue to accelerate to reach a top speed of 29.5 m/s. Assume the acceleration is constant until the top speed is reached and is zero thereafter. Let the +?-direction point in the direction the cheetah runs.
