Question

a bus travelling at constant speed of 81km/hr roinds a curve of radius 200m what is its centripetal acceleration?
​

Answer 1

Answer:

Hey mate here is your answer.//

Explanation:

The tangential velocity around the curve remains constant.

Velocity is a vector with a magnitude and a direction. Acceleration occurs when either the magnitude or direction of velocity change (or both simultaneously). The magnitude is known as speed.

In this problem, the magnitude is 90km/h. As the car rounds the bend its speed remains constant, but its direction changes constantly. The force that causes this acceleration is known as the centripetal (centre seeking) force, and the associated acceleration is called normal acceleration. This acceleration is also a vector and its direction is toward the centre of the curve. The magnitude of this acceleration is a = (v^2)/r, where v is the tangential velocity, and r is the radius of the curve.
