A body starts with an initial velocity of 20 m/s and moves with a uniform acceleration, a, for 15 seconds. Which of the following equations represents the distance, S, traveled?
300 + 56a2
300 + 225a2
300 + 2252a
300a + 2252
Correct answer is B
u = 20 ms-1, t = 15 s
S=ut+1/2at2
S = 20(15) + 12×a×152
∴ S = 300 + 225a2
