Problem 13E

Starting from rest, one car accelerates to a speed of 50 km/h, and another car accelerates to a speed of 60 km/h. Can you say which car underwent the greater acceleration? Why or why not?

Step-by-Step Solution:
Step 1 of 3

Initially both car's at rest, Initial velocity of the car 1,u1=0 m/s Initial velocity of the car 2,u2=0 m/s Final velocity of the car 1,v =50 km/h 1 Final velocity of the car 2,v 260 km/h Now acceleration of the car 1, vu a= t 50 = 60×60 =0.0138 m /s 2 Now acceleration of the car 2, vu a= t 60 = 60×60 =0.0166 m /s 2 Acceleration of car 2 is greater than acceleration of 1 Because Change in velocity is more of car 2 than car 1
