Question

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 in a certain direction with an acceleration
in the perpendicular direction,
​

Answer 1

Explanation:

(a) One example of this is vertical particle projection. When an object is thrown upwards, the maximum height velocity of the body is zero, but constant acceleration due to gravity is still working. ... The object can move in a certain path with a perpendicular acceleration, in the case of circular motion.

(b) an object moving in a certain direction with acceleration in the perpendicular direction. Answer: ... When an object is moving along a circular motion its path is along the circle tangent but the centripetal acceleration is towards the circle radius.
