Answer:

Obtain a relation for the DISTANCE travelled by an object moving with a UNIFORM ACCELERATION in the INTERVAL between 4th and 5th seconds.

Using the equation of MOTION s = ut + at 1/ 2 at2

Distance travelled in 5 s

s = u × 5 +1/2 a × 52

or s = 5 u + 25/ 2 a ——(i)

Similarly, distance travelled in 4 s, s′ = 4 u + 16/ 2 a——(ii)

Distance travelled in the interval between 4th and 5th second

= (s – s′) = (u +9/2 a)m
