At a certain instant an auto driver is driving at a speed of 30km/hr t

1.	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» 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. :))

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.
