A cheetah is crouched 20 m to the east of an observer. At time t = 0 s, the cheetah begins to run due east
toward an antelope that is 50 m to the east of the observer. During the first 2.0 s of the attack, the cheetah's
coordinate x varies with time according to the equation x = 20 + 5t?.
(a) Find the cheetah's displacement between t1 = 1.0 s and t2 = 2.0 s.
(b) Find its average velocity during that interval.
(c) Derive an expression for the cheetah's instantaneous velocity as a function of time, and use it to
find Vy at t = 1.0 s and t = 2.0 s.

One lane of the three lanes on a section of this freeway will have to be closed to undertake an emergency bridge repair that is expected to take 2 hours. It is estimated that the capacity at the work zone will be reduced by 30 percent of that of the section just upstream of the work zone. The mean free flow speed of the highway is 70 mi/h and the jam density is 150 veh/mi/In. If it is estimated that the demand flow on the highway during the emergency repairs is 85 percent of the capacity, using the deterministic approach, determine the following.
