If the net force acting on a moving object is zero, the object will: * slow down and, eventually, stop.
continue at the same speed but change direction.
O
continue in the same direction but change speed.
O
continue in the same direction with no change of speed.

D) continue in the same direction with no change of speed.

In other words, the velocity of the object won't change.

A net force of 0 means that all forces acting on the object are in balance. If the object is in motion, then it stays in motion. If the object is at rest, then it stays at rest. This is newton's first law of motion describing inertia.

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
