To calculate the time it takes for the soccer ball to come to a complete stop, you can use the formula: final velocity = initial velocity + (acceleration x time). In this case, the final velocity is 0 m/s (since the ball comes to a stop), the initial velocity is 4 m/s, and the acceleration is -0.3 m/s^2. Rearranging the formula to solve for time, you would get: time = (final velocity - initial velocity) / acceleration. Plugging in the values, you would get: time = (0 - 4) / -0.3 = 13.33 seconds. So, it will take approximately 13.33 seconds for the ball to come to a complete stop.

Describe a situation in which the car has zero speed but has a definite acceleration?
A car at rest on an incline will have zero speed but a definite acceleration due to gravity pulling it downhill. This acceleration is constant as the car gains speed while rolling down the slope, even though its initial velocity was zero.
What happens to the velocity of a ball that is rolling down a hill?
The velocity of a ball rolling down a hill will increase due to the acceleration caused by the pull of gravity. As the ball gains speed, its velocity will continue to increase until it reaches the bottom of the hill.
Is a ball rolling an example of acceleration?
Yes, a ball rolling is an example of acceleration. As the ball rolls, its velocity changes, which means it is accelerating. This acceleration is caused by a change in its speed or direction of motion.
If a ball is rolling in a straight line and you push it to the right velocity Will?
If you push the ball to the right velocity in the same direction, it will continue moving in a straight line with the new velocity. If there are no other forces acting on it, it will maintain constant velocity due to inertia.
How can an object moving at a constant speed have a nonzero acceleration?
Let's review some terms before we tackle this one. Speed is displacement per unit of time. We know 60 miles per hour is a speed. Velocity is speed with a direction vector associated with it. We know 60 miles per hour east is velocity. Acceleration is a change in velocity. That means if an object changes its speed or its direction or both, it is accelerating.If an object has a given velocity and it slows down or speeds up, it is accelerated. But if the same object changes direction without a change in speed, it is still experiencing acceleration. A force had to act on the object to change its direction, even though its speed didn't change. Thus, an object can accelerate even though it does not change speed.
Descrbe a real world situation where there is zero acceleration but some velocity.?
-- a car on cruise control rolling along at a constant speed on a straight section of highway -- a golf ball or squash ball rolling across the gym floor at a constant speed

Does rolling friction always reduce the net force acting on against an objects motion to zero?
The net force will be zero only if the velocity is constant, which means acceleration is zero.
How acceleration occur in a straight pattern?
It just does, in the absence of other forces ( ie air and rolling resistance ), that is to say under ideal conditions, a constant force on a fixed mass will produce uniform acceleration (velocity change) acceleration ( (m/s)/s ) = force (newtons) / mass (kg)

What is the eq of constant for a sphere rolling in a frictional less incline surface?
The equation for the constant acceleration of a sphere rolling without slipping on a frictionless inclined plane is given by a = g * sin(theta) / (1 + (I / (m * r^2))), where a is the acceleration, g is the acceleration due to gravity, theta is the angle of the incline, I is the moment of inertia of the sphere, m is the mass of the sphere, and r is the radius of the sphere.
Three things that can be acceleration?
A car speeding up on a highway. A ball rolling down a slope. A rocket launching into space.
Motion with constant velocity is a special case of motion with constant acceleration?
No, motion with constant velocity is a special case of motion with zero acceleration. In this scenario, the speed of an object remains constant over time. Constant acceleration, on the other hand, involves a change in velocity over time.
What is the state of equilibrium of a rolling ball?
The state of equilibrium of a rolling ball occurs when the forces acting on it are balanced, resulting in no acceleration. In this state, the ball will continue rolling at a constant speed in a straight line unless acted upon by an external force.
