Refer to a 5-m ladder sliding down a wall, as in Figures 5 and 6. The variable h is the height of the ladder’s top at time t, and x is the distance from the wall to the ladder’s bottom.

Figure 5

Figure 6

Assume the bottom slides away from the wall at a rate of 0.8 m/s. Find the velocity of the top of the ladder at t = 2 s if the bottom is 1.5 m from the wall at t = 0 s.
