A car is traveling at 50 mi/h when the brakes are completely applied, producing a constant deceleration of 28ft/s2. What is the distance covered before the car comes to a stop? (Give your answers correct to one decimal place.)
As a sailboat sails 58.5 m due north, a breeze exerts a constant force F1 on the boats sails. This force isdirected at an angle west of due north. A force of F2 of the same magnitude directed due north would do the same amount of work on a sail boat..
