Question

Obtain a relation for the distance travelled by an object moving with a uniform acceleration in the intervalbetween t=4 and t=5 seconds

Answer 1

1 Answer

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.
