Question

a car starts from rest and attains a velocity of 30 Km/h in 10 sec. Calculate it's acceleration.
​

Answer 1

Answer:

Explanation:a car starts from rest

Then initial velocity=0

And Attains a velocity= 30km/hr

Now convert it in m/sec multiply by 5/18

Final velocity(V)= 30×5/18 = 150/18

V= 8.3m/sec

T= 10sec

Now ,

Acceleration = V-U/t

a= 8.3-0/10

a=.83m/sec*2
