Given data :- A car is travelling at 30 m/s on a circular road of radius 50 m. It is increasing in speed at the rate of 2 m/s².
To find :- Car's acceleration ?
Solution :- According to given,
Here,
→ velocity of car = 30 m/s
→ radius of road = 50 m
Let, tangential acceleration be 2 m/s²
Now,
→ centripetal acceleration = v²/r
→ centripetal acceleration = (30)²/50
→ centripetal acceleration = 900/50
→ centripetal acceleration = 18 m/s²
Now, we need to calculate net acceleration:
Hence, acceleration of car is 2√82 m/s².
{ Note :- 2√82 m/s² = 18.1107 m/s² }
