Explanation:
Cheetah kinematic
The cheetah moves with uniformly accelerated movement, and the formulas that describe this movement are:
d= v₀*t + (1/2)*a*t² Formula (1)
vf²=v₀²+2*a*d Formula (2)
vf=v₀+a*t Formula (3)
Where:
d:distance in meters (m)
v₀: initial speed in m/s
vf: final speed in m/s
a: acceleration in m/s²
t: time in seconds (s)
Known Data
v₀ =0
a = 4.5 m/s²
vf= 30 m/s.
Problem development
We apply the formula (2) that has known data to calculate the distance :
vf²=v₀²+2*a*d
(30)²= 0 + 2* 4.5* d
d= 100m

Explanation:
From the question we are told that
The speed of the car is
The length of the ramp is
The constant velocity of the traffic
Generally the acceleration of the car is mathematically represented as
Here u is equal to zero given that the car started from rest so
=>
Generally the time taken is mathematically represented as
=>
=>
The distance traveled by the traffic is mathematically represented as
Here a is zero given that the traffic was moving at constant speed
=>
=>
