Problem

The following data were obtained while dropping a metal ball near Earth’s surface: Time

t

(s): 0, 1, 2, 3 Velocity

v

(m/s): 0, 9.8, 19.6, 29.4 From the slope of the

v

–

t

graph, the acceleration of the ball is approximately a)

14.7\,\text{m/s}^2

9.8\,\text{m/s}^2

4.9\,\text{m/s}^2

19.6\,\text{m/s}^2
