No i took the test and the answer is actually homogenous mixture
Inertia is the force in play here
Answer
given,
initial speed of the car = 90 m/s
final speed of the car = 0 m/s
distance taken to stop = 110 m
calculating the acceleration of the car = ?
using the equation of motion
v² - u² = 2 a s
0² - 90² = 2 x a x 100

a = 40.5 m/s²
acceleration of the formula one car is equal to a = 40.5 m/s²

Answer:
L=55.9m
Explanation:
The equation for the period of a simple pendulum is:

In our case what we know is the period and the acceleration of gravity, and we need to know the length of the pendulum, so we can write:

Which for our values is:
