Answer:
160 m/s
Explanation:
The Ferrari is moving by uniformly accelerated motion, with constant acceleration of a = 50 m/s^2, and initial velocity u = 10 m/s. The velocity at time t of the car is given by

where
u = 10 m/s
a = 50 m/s^2
If we substitute t = 3 s into the equation, we can find the velocity of the car after 3 seconds:

A. the medium
For refraction to occur, there has to be change from one medium to another. For example rays of light would refract as the travel from air to water.
