Answer 1

Answer:

Velocity is the rate of change of displacement.

Mathematically, this is expressed as

v=ds/dt

Rearranging the equation, we get

ds=vdt

Substituting the first equation of motion in the above equation, we get

ds=(u+at)dt

ds=(u+at)dt=(udt+atdt)

On further simplification, the equation becomes:

∫s0ds=∫t0udt+∫t0atdt

=ut+1/2at2
