**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

[tex]v(t)= u +at[/tex]

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:

[tex]v(3 s)=10 m/s + (50 m/s^2)(3 s)=160 m/s[/tex]
