Q 11-05-105JEE MainJEE Main 2023 (12 Apr, Shift 1)Easy
Given below are two statements:
**Statement I:** A truck and a car moving with same kinetic energy are brought to rest by applying brakes which provide equal retarding forces. Both come to rest in equal distance.
**Statement II:** A car moving towards east takes a turn and moves towards north, the speed remains unchanged. The acceleration of the car is zero.
In the light of given statements, choose the most appropriate answer from the options given below.
Answer: (A) Statement I is correct but Statement II is incorrect
Work–energy: $Fd=K$, so equal $K$ and equal $F$ give equal stopping distances (I correct). Turning changes the direction of velocity, so there is an acceleration (II incorrect).
