a car has an acceleration of 4 m/s squared. What will the increase in it's velocity be after 2 seconds? If it started with a velocity of 30 m/s, what is its final velocity?

To find the increase in velocity of the car after 2 seconds, you can use the equation of motion:

v = u + at

Where:
v = final velocity
u = initial velocity
a = acceleration
t = time

Given:
u = 30 m/s (initial velocity)
a = 4 m/s^2 (acceleration)
t = 2 seconds (time)

Substituting the given values into the equation, we can calculate the final velocity:

v = 30 m/s + (4 m/s^2)(2 s)
v = 30 m/s + 8 m/s
v = 38 m/s

Therefore, the increase in velocity after 2 seconds is 8 m/s, and the final velocity of the car is 38 m/s.
