To determine the final velocity of the car after 10 seconds, we can use the equation:
v = u + at
where: v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time.
Given: u = 3 m/s (initial velocity) a = 4 m/s² (acceleration) t = 10 s (time)
Plugging in the values into the equation, we get:
v = 3 m/s + (4 m/s²)(10 s) = 3 m/s + 40 m/s = 43 m/s
Therefore, the car will be moving at a velocity of 43 m/s after 10 seconds.
