A car moves with an initial velocity of 25 ms\(^{-1}\) and reaches a velocity of 45 ms\(^{-1}\) in 10s. What is the acceleration of the car?
A
2 ms-2
B
5 ms-2
C
20 ms-2
D
25 ms-2
Verified Correct Answer: A.
Physical Principles & Numerical Solution
Acceleration = (increase in velocity)/time taken
= (45 - 25)/10 = (20)/10 = 2ms-2
