When the body is projected vertically upward then at the highest point its velocity is zero but acceleration is not equal to zero ( g =9.8 m / s 2).

When the body is projected vertically upward then at the highest point its velocity is zero but acceleration is not equal to zero (g=9.8m/s2).

When the body is projected vertically upward then at the highest point its velocity is zero but acceleration is not equal to zero $(g = 9.8 m / s^{2})$ .
