What else can I help you with?
How does the coefficient of kinetic friction vary with the the area of contact between the block and he horizontal?
The coefficient of kinetic friction remains constant regardless of the area of contact between the block and the horizontal surface. It is a property of the materials in contact and does not depend on the surface area.
In the absence of air friction does the horizontal component of a projectile?
The horizontal component of a projectile's velocity remains constant in the absence of air friction. This means the projectile will continue to move horizontally at a constant speed unless acted upon by an external force.
What remains constant in simple harmonic motion if friction is ignored?
In simple harmonic motion, the frequency remains constant if friction is ignored.
When you push with a horizontal 10-N force on a book that remains at rest what is the force friction?
The force of friction acting on the book will be equal in magnitude but opposite in direction to the applied force, so it will also be 10 N. This is necessary to keep the book at rest as there is no net force acting on it.
Is friction a greater force when motion is faster?
Friction is not affected by the speed of motion. The force of friction remains constant regardless of the speed of the objects in contact.

What do the horizontal motions of a projectile have in common?
The horizontal motions of a projectile are independent of its vertical motion. This means that the horizontal velocity remains constant and unaffected by gravity. Additionally, the horizontal distance traveled by a projectile is determined by the initial horizontal velocity and the time of flight.
A rope exerts a force of magnitude 21 N at an angle 31 deg above the horizontal on a box at rest on a horizontal floor?
A rope exerts a force of magnitude 21 N, at an angle 31 deg above the horizontal, on a box at rest on a horizontal floor. The coefficients of friction between the box and floor are Us = 0.55 and UK = 0.50. The box remains at rest. Determine the smallest possible mass of the box. this is the full question thanks for any help! :)
Why the horizontal velocity component remains constant and the vertical velocity component continuously changes during projectile motion?
The horizontal velocity component remains constant because there are no horizontal forces acting on the projectile (assuming no air resistance), so the velocity remains unchanged. The vertical velocity component changes due to the force of gravity, which accelerates the projectile downward, increasing its velocity as it falls.
Which information is needed to determine the horizontal distance a projectile travels?
-- the initial horizontal speed of the projectile -- the time it remains in flight before it hits the ground
What is a real world situation that you can model with a horizontal line?
It is the model of something which is and remains constant.
What is the value of constant horizontal velocity?
In projectile motion, since , there's no force in the horizontal direction which can change the horizontal motion therefore the horizotal velocity remains conserved Vx=Vox= Vocos theta by using above formula , constant horizontal initial or final velocity can be found. since Initial = final horizontal velocity.
Is horizontal component of velocity is constant for ball thrown upward?
No, the horizontal component of velocity remains constant for an object in projectile motion as long as no external forces act horizontally on the object. In the case of a ball thrown upward, the horizontal component of velocity remains unchanged unless affected by air resistance or other external forces.
