Question

Prove that v= u+ at, where the symbols have usual meaning

Answer 1

Vector V = Vector U + Vector at

t1 = 0

t2 = t

initial velocity = u

final velocity = v

        Vector a = dv/dt

integration dv = integration adt

limits for dv is u to v and limits for adt is from 0 to t

hence, v - u = at

v = u +at (note, only if a is constant)
