A cheetah is squatted 25m to the east of a vehicle. Attime t = 0 the cheetah begins to run due east toward an antelope thatis 55m to the east of the vehicle. During the first 2.0 s of the chase,the cheetah’s x-coordinate varies with time according to the equationx = 25m + (4.5m/s2 )t2. (a) Find the cheetah’s displacement between t1= 1.5s and t2 = 3.0 s. (b) Find its average velocity duringthat interval. (c) Find its instantaneous velocity at t= 2.5s by taking Δt = 0.15s
