1. State which of the following situations are possible
and give an example for each of them.
a. A body with an acceleration but with zero
velocity
b. A body moving horizontally with an
acceleration in vertical direction.
c. A body moving with a constant velocity in an
accelerated motion.​

Answer 1

Answer:

1) Possible

When a body is thrown vertically upward in space, then at the highest point, the body has zero velocity but the acceleration of the body will be equal to the acceleration due to gravity. ...  

2)

possible

A body moving horizontally with acceleration in the vertical direction is possible in a projectile motion.

in projection bod follows the parabolic path with acceleration acting vertically downwards(gravity) at time of decent n supplied acc. (time of accent)

3)

Yes, for e.g. in a circular motion if one is moving with a constant speed, the motion is still said to be accelerated motion as the direction of velocity changes at every point of the path.
