Question

A particle having initial velocity u is moving with a constant acceleration a for time t .find the displacement of the particle in the last one second .
what is the concept behind this?

Answer 1

Explanation:

given,

u=u

t=1

v=0

s=?

s=ut +1÷2a(t square )

a=(v-u)÷t =-u

s=u(1) +1÷2(-u)(1)

s=u-(1÷2)u

s=1/2 u
