Chapter 5: Exercises with Solutions

Section 5.5 Motion 5215.5 ExercisesIn Exercises 1-12, write down the formulad = vt and solve for the unknownquantity in the problem. Once that iscompleted, substitute the known quantitiesin the result and simplify. Makesure to check that your units cancel andprovide the appropriate units for your solution.1.
