Question

9. State which of the following situations are possible and give
an example for each of these:
(a) an object with a constant acceleration but with zero velocity
(b) an object moving with an acceleration but with uniform
speed.
Vc) an object moving in a certain direction with an
acceleration in the perpendicular direction.​

Answer 1

Answer:

(b) an object moving with an acceleration but with yniform

Answer 2

Answer:

Statement (a) is possible

Explanation:

U see the moon rotating around the earth.

Assume that the moon is rotating in a circular orbit. Everytime the moon moves, it faces an acceleration since the orbit is not straight. Drawing a tangent along the motion of the moon, u will see the moon tries to move along the direction of the tangent so that it can gain a uniform velocity. Since the orbit is circular, the moon has an acceleration everytime and thus it has no velocity
