Question

When the distance travelled by a body is directly proportional to the time, it is travelling with -
A--uniform acceleration
B--non uniform acceleration
C--constant speed
D--variable speed

Answer 1

Constant speed

$....$

Answer 2

C--constant speed

S is directly proportional to the time only when there is no external force acting on it. Since acceleration is zero so speed 'u' of the object remains constant. Hence, it can be concluded that S is directly proportional to it.
