To find the velocity of a car after a given time when it accelerates uniformly, you can use the equation:
v = u + at
Where: v = final velocity u = initial velocity a = acceleration t = time
In this case, the car starts from rest, so the initial velocity (u) is 0 m/s. The acceleration (a) is given as 5 m/s². The time (t) is given as 10 seconds. Plugging these values into the equation:
v = 0 + 5 * 10
v = 0 + 50
v = 50 m/s
Therefore, the velocity of the car after 10 seconds is 50 m/s.
