Hey!!!
50 points......
state which of the following situations are possible and give an example of each:
a) A body moving with constant acceleration but with zero velocity.
b) A body moving horizontally with acceleration in vertical direction.
c) A body moving with a constant speed in an accelerated motion.
Remember to explain it with an example........
best answer will be marked as brainlist.
wrong and incomplete answer will be reported.....so be careful.

(a) this is impossible .
because if a body is moving it need to have some velocity as nothing could move with zedo velocity except expanding universe .
(b)yes it is possible .
when a child pulls a toy car attached to rope , he lifts the rope above the ground and pull it making x-compontent of acceleration in vertical direction which is balanced by weight of car hence the car doesnt gain any velocity in vertical direction .and the y-component of acceleration is in horizontal direction which is opposed by friction but still friction is very low so the toy car moves in horizontal direction .
(c) it is also not possible .
because if a body is moving with constant velocity then (v-u)final velocity - initial velocity is zero . hence acceleration needs to be zero because of laws of motion ...
HOPE IT HELPS
PLZZ MARK AS BRAINLIEST ..
Only situation (b) is possible .
When a child pulls a car he makes an angle of 60° but it moves horizontally
