A cheetah is crouched 20 m to the east of an observer. At time t=0 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=20m+(5.0 ms−2)t²
Find the cheetah's displacement between t1=1.0 s and t2=2.0 s
