Problem 9 - Entrance Test

A car is moving with a velocity of 10 m/s and accelerates uniformly at a rate of 2 m/s². What will be its velocity after 5 seconds?

Correct: B

Using the equation v = u + at, where u is the initial velocity, a is the acceleration, and t is the time, we have v = 10 + (2 * 5) = 10 + 10 = 20 m/s.
