When a ball is moving over a horizontal smooth surface with a constant velocity?

When a ball is moving over a horizontal smooth surface with a constant velocity?

As the ball is moving with a constant velocity, therefore there is no acceleration. Thus, balanced forces are acting on the ball.

What is a 0.12 kg ball moving at 6m s when it is hit by a bat?

Final answer: The magnitude of the change in momentum of a 0.12-kg ball that is hit by a bat and reverses direction from 6 m/s to 14 m/s, is 2.4 kg m/s.

What happens to velocity when a ball is thrown horizontally?

The horizontal velocity of a projectile is constant (a never changing in value), There is a vertical acceleration caused by gravity; its value is 9.8 m/s/s, down, The vertical velocity of a projectile changes by 9.8 m/s each second, The horizontal motion of a projectile is independent of its vertical motion.

Why is horizontal velocity constant?

There is only one force acting on the object in the air, that is due to gravity, acting downwards. Since no force is acting in a horizontal direction therefore the magnitude of velocity and angle is remaining constant.

What is the acceleration of a ball with a mass of 0.40 kg is hit with a?

The answer for your question is 40m/second square…

What is the velocity of the 3 kg ball after the collision?

The velocity of the 3 kg ball is 4 m/s after the collision.

What is the kinetic energy of a 2kg ball dropped from a height of 10m?

Now, By the law of the conservation of the Energy, Total amount of the energy of the system remains constant. ∴ Kinetic Energy before the body reaches the ground is equal to the Potential Energy at the height of 10 m. ∴ Kinetic Energy = 980 J.

What is the formula of horizontal projectile?

Formula : Δ x = V x 0 * t .

What is the formula for horizontal motion?

(b) The equation that describes the horizontal motion is x=x0+vxt. x = x 0 + v x t . With x0=0, x 0 = 0 , this equation becomes x=vxt.

What is the formula for horizontal projectile velocity?

Formula: Equations of Motion We can analyze the horizontal and vertical components of the particle’s motion separately. A horizontally projected particle moving freely under gravity has no horizontal acceleration. Therefore, its horizontal velocity does not change, so in the horizontal direction, 𝑣 = 𝑢 and 𝑠 = 𝑢 𝑡 .

What are the three types of projectile motion?

There are three types of projectile motions- Oblique Projectile Motion, Horizontal Projectile Motion, and Projectile Motion on an Inclined Plane.

Is horizontal acceleration always 0?

Nothing accelerates a projectile horizontally, so horizontal acceleration is always zero.

Is acceleration vertical or horizontal?

It is easy to forget that horizontal motion has constant velocity (and zero acceleration!) while vertical motion has constant acceleration.

When a ball is moving on a smooth horizontal surface?

Expert-verified answer Balanced force is acting on a ball moving over a horizontal smooth surface with constant velocity. If the resultant of several forces acting on the body is zero, then the forces are known as balanced forces. They don’t change the speed of a moving object.

When a particle is moving in a horizontal circle with constant velocity?

If an object is moving in a horizontal circle at constant speed, the centripetal force does not do work and cannot alter the total mechanical energy of the object. For this reason, the kinetic energy and therefore, the speed of the object will remain constant.

When an object is moving along the horizontal at constant velocity the net force along the horizontal is zero?

According to Newton’s first law of motion, any object moving at constant velocity has no net external force acting upon it, which means that the sum of the forces acting on the object must be zero. The mathematical way to say that no net external force acts on an object is Fnet= 0 or ΣF=0.

When a ball is moving with a constant velocity?

When a ball is moving with a constant velocity, the net force acting on it is zero, as there is no acceleration. When the ball collides with a wall, there is a sudden change in force, as the ball experiences a force from the wall that causes it to change direction.
