A particle of mass m is given an initial speed V_(0) . It experiences a retarding force that is proportional to the speed of the particle (F = aV). a is a constant. (a) Write the dimensional formula of constant a. (b) Using dimensional analysis, derive a formula for stopping time (t) of the particle. Does your formula tell you how 't' depends on initial speed V_(0) ? What can you predict about the constant obtained in the formula ?
