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.
Accuracy
Explanation:
Accuracy is a term that refers to the exactness of a measurement.
Accuracy is the nearness of measured value to the true value.
The difference between the measured value and the true value is the uncertainty in the measurement.
- The closer a measured value is to the true value, the more accurate the measurement is. The lesser the error accrued in the process.
