HELP! A position-time graph is shown below: (2 points)

Which statement accurately describes the speed of the object in the graph above over the four seconds?
O
Speed is increasing
Speed is constant.
Speed is decreasing.
Object is at rest.

speed is increasing.

this is because the graph has a positive slope (due to it going up ), if it were decreasing, the graph would be going down

b would be the answer

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
