A particle is having uniform acceleration. If its displacement from

t

(t+1)

second is

120 \mathrm{~m}

and change in velocity is

50 \mathrm{~m} / \mathrm{s}

. Find its displacement (in

\mathrm{m}

) in

(t+2)

second.

View answer and explanation

Correct option: A

170

Option A (170) is correct because it calculates the displacement in the (t+2)th second using the given acceleration and change in velocity.
