Answer:
A. 24.5 m/s
B. 30.63 m
Explanation:
A. Determination of the vertical velocity of the apple.
Initial velocity (u) =?
Time (t) = 2.5 s
Acceleration due to gravity (g) = 9.8 m/s²
Vertical velocity (v) =?
v = u + gt
v = 0 + (9.8 × 2.5)
v = 0 + 24.5
v = 24.5 m/s
Thus, the vertical velocity of the apple is 24.5 m/s.
B. Determination of how far the apple has fallen.
Time (t) = 2.5 s
Acceleration due to gravity (g) = 9.8 m/s²
Height (h) =.?
h = ½gt²
h = ½ × 9.8 × 2.5²
h = 4.9 × 6.25
h = 30.63 m
Thus, the apple has fallen 30.63 m in 2.5 s.
