A motorist is driving at 25 m/s on the curved road of radius 500 m. He suddenly applies the brakes and that causes the speed to decrease to 15 m/s at the constant rate in 10 seconds. What will be the tangential component (at) and the normal component (an) of acceleration immediately after the application of brakes
1
at = -1 m/s2, an =1 m/s2
2
at = -1m/s2, an = 1.25 m/s2
3
at = -1.25 m/s2, an = 1 m/s2
4
at = -1.25 m/s2, an = 2 m/s2
