The acceleration of a train travelling with speed of 400m/s as it goes round a curve of radius 160m is
Correct answer: A. 1km/s2
- A. 1km/s2
- B. 100m/s2
- C. 10m/s2
- D. 1m/s2
Explanation
The correct answer is Option A: 1 km/s2. The acceleration of the train is correctly calculated using the formula for centripetal acceleration: ac = v2 / r. Plugging in the values of speed (400 m/s) and radius (160 m) gives 1 km/s2. The other options are incorrect because they do not correctly apply the formula for centripetal acceleration.

About Angular and Linear Quantities
Rotational motion relates angular displacement, angular velocity and angular acceleration to linear displacement, tangential velocity and tangential acceleration through the radius. Questions use radians, v equals r omega and tangential acceleration, while distinguishing tangential velocity from centripetal acceleration and angular quantities from their linear counterparts.
