Obtain a relation for the distance travelled by an object moving with a uniform acceleration in the interval between 4th and 5th seconds.
from the equation of motion
s= ut + at2 Distance travelled in 5s,
s = u x 5+ x a x (5)2
s =5u + 25/2 a …….(i)
Similarly, distance travelled in 4s,
s’ =4u +16/2 a
Distance travelled in the interval between 4th and 5th second=(s-s’)
= (5u +25/2 – 4u +8)
= (u+ a) m

There is an argument about uniform acceleration between Mr X and Mr Y. Mr X says “acceleration means that farther you go faster you go”. Mr Y says “acceleration means that longer you go the faster you go”. Whose statement is correct?Evergreen - Science

You are sitting in a stationary car. There is a helium balloon tied to its floor. You accelerate and obviously feel like you are being pushed backwards (against the direction of your accelerations). The balloon.All In One - Science
