Calculating Velocity: Car Accelerating at 2m/s/s for 10 Seconds

To calculate the velocity of the car at the end of 10 seconds, we can use the formula:

v = u + at

where: v = final velocity u = initial velocity (which is 0 m/s since the car starts from rest) a = acceleration (2 m/s/s) t = time (10 seconds)

Plugging in the given values into the formula:

v = 0 + (2 m/s/s)(10 s) v = 0 + 20 m/s v = 20 m/s

Therefore, the velocity of the car at the end of 10 seconds is 20 m/s.
