A construction worker pulls a five-meter plank up the side of a building under construction by means of a rope tied to one end of the plank (see figure). Assume the opposite end of the plank follows a
path perpendicular to the wall of the building and the worker pulls the rope at a rate of 0.29 meter per second. How fast (in m/sec) is the end of the plank sliding along the ground when it is 1.2
meters from the wall of the building? (Round your answer to two decimal places.)

The base of a 20-meter tower is at the origin. The base of a 20-meter tree is at
(0, 20,0). The ground is flat and the z-axis points upward. The following para-
metric equations describe the motion of six projectiles each launched at time t = 0
in seconds.
(I) 7(t) = (20 +t²)E
(II) F(t) = 2t23 + 2t²K
(III) F(t) = 207+ 20 3+ (20 – t²) E
(IV) F(t) = 2t j+ (20 – t2)
(V) F(t) = (20 – 2t) 7+ 2t 3+ (20 – t) k

In one scene Bonnie and Clyde try to flee from one state to another. If they get across the state line, they could evade capture, at least for a while until they become Federal fugitives. In the script, Bonnie is driving down the highway at 108 km/hr and passes a concealed police car that is 1 km from the state line. The instant Bonnie and Clyde pass the patrol car, the cop pulls onto the highway and accelerates at a constant rate of 2 m/s2.
