Can a ball moving in a circle have 424 N of net force acting on it.?

yes it can, the equation involved is :
force (f) = mass(m) * (velocity(v)^2 / radius(r))
say mass = 1 kg, radius = 1 m
then:
424 = 1 * (v^2 / 1)
velocity required to produce this force:
v = sq. root ((424 * 1) / 1)
v= 20.6 metres / sec

How can you tell from the path of the ball that there is another force acting on the ball other than the kicking force?
Inthe kicking force, kinetic energy is acting on the ball together with Gravitational Potential Energy. Whereas the part where aother force is acting on iit while the ball is not moving is alsoocontrolled by gravitaitional potential energy.
If a ball isn't moving which force causes it to start moving?
We might say that an unbalanced force causes a ball to start moving. If a ball is resting on a surface, gravity is pulling down and the surface is pushing up against it. Things (forces) are in balance and the ball is still. Drop the surface out from under the ball and that ball begins to fall as gravity has no opposing force to balance it.Any lateral force on the ball that can overcome its rolling resistance will cause the ball to move. The inertia of the ball is such that it "wants" to remain at rest. Some unbalanced force will have to act on the ball to cause it to start moving. A ball on a pool table sits still until struck by a cue or another ball. It takes an "outside" force to "unbalance" the forces acting on a ball that is at rest to cause it to move.
What force is responsible for a tennis ball moving forward after it gets hit by a tennis racket?
The ball keeps moving forward because of its momentum, which is not a force.
What way is the net force acting on a ball thrown in the air with upward velocity?
net force is non zero because if net force was zero the body would continue to remain at rest according to newtons 1st law....the net force is only due to gravity
When the ball bounces off a wall the net force on the ball is zero because of action and reaction forces?
The net force on the ball is not zero. The ball exerts a force on the wall (the action), and the wall exerts an equal and opposite reaction force on the ball. These two forces do not sum to zero as they are acting on different objects; the action of the ball acts on the wall and the reaction of the wall acts on the ball.
What keeps the force of a ball on a string moving in a circle?
No. The force keeping a ball on a string moving in a circle is centripetal force, i.e. force pulling the ball to the center of the circle.
What force is acting on a ball when it is not moving?
Gravity
The force keeping a ball on a string moving in a circle is called what?
centripetal

What would happen to an object if the centripetal force acting on it stops?
Picture a ball on a string being whirled about the head of an experimenter. If the string breaks, the centripetal force disappears. The ball leaves on a tangent path form its (previous) circular path. Yes, it's that simple. The string provided centripetal force, by virtue of its tensile strength, to the ball to keep that ball moving in a circle. When the string broke, there was no force left to accelerate the ball "in" and keep it moving in an arc.
How does a roulette ball stop?
The roulette ball stays in motion due to centrefugal force. Since the ball is moving fast it "wants" to just go straight (Newton's 1st law) but the contact force of the metal track exerts an inward force that keeps it moving in a circle. Eventually, as the ball loses momentum, the force of gravity will be greater and the ball will then fall into a pocket.

Why would a ball would never stop moving if you give it a push (apply a force to it) in outer space?
There is no force of drag or friction acting to slow it down.

What happen when a ball rolling across the floor shows to stop?
When it stops it stops. Inertia will stop it from moving unless there is some force acting on it.
How will the path of the ball appear to you if you accidentally drop a ball while inside a moving bus?
If the bus is moving at a constant horizontal velocity relative to you and the ball, there is no horizontal acceleration and therefore no horizontal force. The only force acting on the ball is gravity, which is vertical, so the ball will just fall straight down next to you.
Why do moving body accelerate?
Not all moving objects accelerate. In general, an object will accelerate if there is a net force acting on it. For a ball in the air, this might be gravitation + air resistance; for a moving car (once you turn the engine off) it might be the force of friction; etc.
