Question

At a certain instant an auto driver is driving at a speed of 30km/hr then he uniformly accelerates the auto and after 2.5min,the speed of his auto becomes 60km/hr.What is the average speed of the auto? What is the value of uniform acceleration during the given interval of time

Answer 1

Answer:

25 m/s : average velocity

Step-by-step explanation:

the average speed of the auto would be v2 - v1 that is 50/3 -25/3 which is equal to 25/3 m/s

to find the acceleration, apply v=u +at

where v = 60km/hr = 50/3 m/s ( we are taking this as v because the auto stops with this velocity ,I. e., final velocity)

u= 30km/hr =25/3 m/s

time = 2.5 min = 150 seconds..

just substitute and u will get the acceleration..

hope it helped.
