Q23Long answer
Obtain a relation for the distance travelled by an object moving with a uniform acceleration in the interval between 4th and 5th seconds.
Show answer
Using the equation of motion s = ut + at 1 2 Distance travelled in 5 s s = u ×5+ a × 5 or s =5u+ a ——(i) Similarly, distance travelled in 4 s, s′ = 4 u + a——(ii) Distance travelled in the interval between 4th and 5th second = (s – s′) = ( u + a) m u2 - v2
