A car speed increases from 40 km/hr to km/hr in 5 sec. Calcuate the acceleration of car:
1 answer:
Answer:
14400km/h
Step-by-step explanation:
Given that
The speed of the car increased from 40 km/hr to 60 km/hr
And, the time taken is 5 seconds
we need to find out the acceleration of the car
So,
Here
u = initial velocity =40km/h
v = final velocity =60km/h
t = time = 5s =5 ÷ 3600h
a = acceleration
Now as we know that
a = (v - u) ÷ t
= (60 - 40) ÷ (5 ÷ 3600)
= (20 × 3600) ÷ 5
= 14400km/h
