To determine the velocity of the car at the end of one second and two seconds, we can use the equation of motion that relates velocity (v), initial velocity (u), acceleration (a), and time (t):
v = u + at
Given that the acceleration of the car is 2 m/s² and the initial velocity is 10 m/s, we can substitute these values into the equation.
At the end of one second (t = 1 second):
v = 10 + 2 * 1 v = 10 + 2 v = 12 m/s
Therefore, the velocity of the car at the end of one second is 12 m/s.
At the end of two seconds (t = 2 seconds):
v = 10 + 2 * 2 v = 10 + 4 v = 14 m/s
Therefore, the velocity of the car at the end of two seconds is 14 m/s.
