Question 21
Easy

A small rubber ball is dropped from a height and bounces several times on a hard floor.

Figure 1 shows how the height of the ball above the floor changes with time.

A line graph showing the height of a rubber ball in meters against time in seconds. The y-axis is labeled 'Height (m)' and has scale markers from 0.0 to 2.0 with major subdivisions every 0.2 m. The x-axis is labeled 'Time (s)' and ranges from 0.0 to 3.0 seconds with subdivisions. The curve starts at a height of 1.8 m at 0.0 s, curving down to meet the floor (0.0 m) at 0.6 s. The first bounce curves upwards to a peak at exactly 1.2 m at a time of 1.2 s, before falling back to the floor at 1.8 s. The second bounce curves up to a peak of 0.8 m at 2.3 s before falling back to the floor at 2.8 s.

Use Figure 1 to estimate the maximum height that the ball reaches after the first bounce.
