Question

1) State which of the following situations are possible and give an example of each of these:
a) a body moving with constant 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

c) is possible during the rotational motion with constant angular velocity. Then there is centripetal acceleration, but the value of the velocity is constant.

For b), when a charged particle moves horizontally through a magnetic field which is also horizontal but perpendicular to its path, the particle will be accelerated in the vertical direction.

a) is not possible.

Answer 2

Thanks a lot!!1
