Question

the graph shows the height h, in meters, of a shot put at time t, in seconds, from the moment it was launched at ground level. Estimate the average rate of change in height from t= 0.2 seconds to t= 0.6 seconds.

Answer 1

about 6 m/s

Explanation:

It looks like the height may have changed from about 1.8 m to 4.2 m in those 0.4 seconds, so the average rate of change is ...

(4.2 -1.8)m/(0.4 s) = (2.4 m)/(0.4 s) = 6 m/s
