The initial velocity of a body moving along a straight line is 7 m/s. It has a uniform acceleration of 4 m/s 2 . The distance covered by the body in the 5 th second of its motion is
Text Solution
Verified by ExpertsThe correct answer is:
A
Distance covered by the body in the 5th second
S n = u + 
(2n – 1)
= 7 + 
(2 × 5 – 1)
= 7 + 2 (10 – 1)
= 7 + 18
= 25 M
