Question
A body, moving in a straight line, with an initial velocity u and a constant acceleration a, covers a distance of 40 m in the 4^{th} second and a distance of 60 m in the 6^{th} second. The values of u and a respectively are




None of these
easy
Solution
Given,
and
These equations give u = 5 ms^{–1} and a = 10 ms^{–2}.
