A small object of mass 50 g is released from a point A. Determine the velocity of the object when it reaches a point B, a vertical distance of 30m below A. [g = 10 ms−2
1.5 ms−1
6.0 m s−1
17.3 m s−1
24.5 m s−1
Correct answer is D
v = ?, u = 0, a = 10, s = 30
V² = U²+2as
V² = 0 + 2 * 10 * 30
V² = 0 + 600
V = √600
V = 24.5m/s
