Question
-A sports car has an average acceleration of 13.1miles/hour/sec. how long does it take for the car to reach 60 mi/h,if it starts from rest? -Acceleration is sometimes expressed in multiples of g, whereg= 9.8 m/s^2 is the acceleration due to the earth's gravity. In acar crash, the car's velocity may go from 26 m/s to 0 m/s in .15s.How many g's are experienced, on average, by the driver? -A sports car has an average acceleration of 13.1miles/hour/sec. how long does it take for the car to reach 60 mi/h,if it starts from rest? -Acceleration is sometimes expressed in multiples of g, whereg= 9.8 m/s^2 is the acceleration due to the earth's gravity.

(1) Given that the averageacceleration a = 13.1 miles/hour2 Initial velocity is U = 0 mi/h Finalvelocity is V = 60 mi/h Fromthe equation of motion time taken is t = ( V - U) / a = ------ sec (2) Given that the iniital velocity is U = 26m/s Finalvelocity is V = 0 m/s Timetaken is t = 0.15s accelarationis a = ( V -U ) /t = ----------- m/s2 Then numberof g's is N = a /g =---------- Initial velocity is U = 0 mi/h Finalvelocity is V = 60 mi/h Fromthe equation of motion time taken is t = ( V - U) / a = ------ sec (2) Given that the iniital velocity is U = 26m/s Finalvelocity is V = 0 m/s Timetaken is t = 0.15s accelarationis a = ( V -U ) /t = ----------- m/s2 Then numberof g's is N = a /g =----------Related Questions
