A car starts from rest and accelerates uniformly at 2 m/s² for 5 seconds. What is the car's velocity at the end of this time interval?
A.5 m/s
B.10 m/s
C.15 m/s
D.20 m/s
Explanation
Core Concept
Using the kinematic equation v = u + at, where u = 0 m/s (initial velocity), a = 2 m/s² (acceleration), and t = 5 s (time), we get v = 0 + (2)(5) = 10 m/s.
Correct Answer
B10 m/s
