Question

a ball is not dropped, but is thrown up towards the motion sensor, from an initial position near the floor. A plot of velocity (m/s) vs. time (s) is made using DataStudio for the time when the ball is on its way up. The fit yields a slope of 10.4 +0.28 and an intercept of -14.5+0.31.

Based on the data, what would we report as the mean value of the acceleration of the ball due to its gravitational attraction to the earth?

a) 10.4 m/s2

b) 9.67 m/s2

c) 9.81 m/s2

d) 10.4 m/s

e) 9.81 m/s

a) 10.4 m/s2

b) 9.67 m/s2

c) 9.81 m/s2

d) 10.4 m/s

e) 9.81 m/s

Explanation / Answer
