Question

The distance travelled by a body is given as x = t² . The motion of the body is
a. Uniform Motion
b. Uniformly Accelerated Motion
c. Non Uniform Acceleration
d. None of these

Answer 1

The distance travelled by a body is given as x = t² . The motion of the body is Uniform motion

Answer 2

Answer: b. Uniform accelerated motion

Explanation:

Given x = t²

Differentiating twice both the sides w.r.t. t we get d²x/dt² = 2 or a = 2

Clearly the acceleration is a constant, not dependent on time . So the motion of the body is uniformly accelerated
