Question

If the displacement of a body varies as the square of elapsed time, then its (A) velocity is constant (B) velocity varies non-uniformly (C) acceleration is constant (D) acceleration changes continuously

Tardigrade Admin · Accepted Answer

If the displacement of a body varies as the square of elapsed time, then its acceleration is constant, i.e. S=(1/2) a t2

Q. If the displacement of a body varies as the square of elapsed time, then its

velocity is constant

velocity varies non-uniformly

acceleration is constant

acceleration changes continuously

momentum is constant

If the displacement of a body varies as the square of elapsed time, then its acceleration is constant, i.e. $S = \frac{1}{2} a t^{2}$
