Answer:
4 m
Explanation:
From the question given above, the following data were obtained:
Initial velocity (u) = 10 m/s
Acceleration (a) = –8m/s²
Time (t) = 2 s
Displacement (s) =?
The displacement of the object can be obtained as follow:
s = ut + ½at²
s = (10 × 2) + (½ × –8 × 2²)
s = 20 + (–4 × 4)
s = 20 + (–16)
s = 20 – 16
s = 4 m
Thus, the displacement of the object is 4 m.
