A stone is projected from ground. Its path is as shown in figure. At which point its speed is decreasing at fastest rate?
1 \(A\)
2 \(B\)
3 \(C\)
4 \(D\)
Explanation:
The speed of a projectile decreases fastest right after it is launched due to the immediate effect of gravity acting against its initial upward velocity. Thus, at point A, the stone's speed is decreasing at the fastest rate. Correct option is (1).
