Question

Tum in this sheet only De not attach another sheet. Show details or your solution provide answer with proper number of significant figures Problem: A car starts from a stop sign and accelerates for& 00 seconds along straight leveled road (in』 section called section I) till it reaches a coasting speed of vir 30.1 miles per hour In the next section (section including the besic equations, unith and Il) of the road the applies breaks at 1.50 m/sl eventualy stopping at the nest stop sign car continues to coast for 16.6 seconds. Then in the next section (section II) the driver (a) Calculate vir (in m/s) (b) Calculate (in mass)-nt (c) Calculate (in meters) Ax (d) Calculate the time Calculate average velocity for the whole trip - (e) Draw a graph of x versus t (choose a proper scale and label everything including the sections) (0) Draw a graph of v versus t (choose a proper scale and label everything including the sections).

Please give a detailed explanation and equations used.
