What force is needed to slide a wooden block having a mass of 300 slugs moving across a floor if the friction is 0.80?
The force needed to slide the wooden block can be calculated using the formula: force = friction coefficient * mass * gravity. Given that the mass is 300 slugs and the friction coefficient is 0.80, the force required will be 2400 lbs.
The driving force of a reaction is the change in?
The driving force of a reaction is the change in free energy. This change determines whether a reaction will proceed spontaneously or require external energy input. A negative change in free energy indicates a spontaneous reaction, while a positive change requires energy input.
A blocks weight is 36.0 N rests on horizontal table A horizontal f. of 42 N is applied to the block coefficients of static and kinetic fric are 0.650 and 0.420 resp Will the block move under force?
In order for the block to move the force applied has to be greater than the maximum force of static friction. F > fs fs = coefficient of friction * normal force = .65 * 36N // you can use the weight for the normal force since the block is being supported = 23.4N Since applied force of 42N is greater than the 23.4N due to friction, the block will start sliding, where kinetic friction will act on the block.
A block of mass M is pulled with a rope on a frictionless surface If a force P is applied at the free end of the rope what will be the force exerted by the rope on the block if the mass of rope is m?
A block of mass M is pulled with a rope on a frictionless surface If a force P is applied at the free end of the rope what will be the force exerted by the rope on the block if the mass of rope is m? Equation#1: Force = mass * acceleration The force P pulls a total mass of (M + m) accelerating both masses at the same rate. Equation #2: P = (M + m) * a Equation #3: a = P ÷ (M + m) At the point where the rope is attached to the block, the block of mass M feels a force making it accelerate at a rate of a = P ÷ (M + m). The force required to make at block of mass M accelerate at a rate of a = P ÷ (M + m) can be determined by equation #4. Equation #4: F of block = mass of block * [P ÷ (M + m)].
A sprinter of a mass 65.0 kg starts his race by pushing horizontally backward on the starting blocks with a force of 200 N What force causes him to accelerate out of the block?
The force of static friction between the sprinter's foot and the starting block causes him to accelerate out of the block. The static friction force acts forward on the sprinter, helping him overcome the backward force he exerts on the starting blocks.
Why does wooden block have higer bouyant force than metal block?
It doesn't. Assuming the volumes are the same, the buyant force will also be the same.
What are the variables that determine the force of friction between a wooden block and the surface on which it is resting?
The force of friction between a wooden block and a surface is determined by the normal force pressing the block onto the surface and the friction coefficient between the two materials. Additionally, the surface area of contact and the roughness of the surfaces can also influence the force of friction.
What force would be required to pull a 10.0 kg wooden block at a constant velocity on Jupiter?
The force required to pull a 10.0 kg wooden block at a constant velocity on Jupiter would be determined by the gravitational force on Jupiter, which is approximately 24.79 m/s^2. Using the formula F = ma, where F is the force, m is the mass, and a is the acceleration due to gravity on Jupiter, the force required would be approximately 247.9 N.
How do you demonstrate an experiment to show that friction is a contact force?
To demonstrate that friction is a contact force, you can place a wooden block on a flat surface and try to slide it. Then, place a heavier block on the wooden block and attempt to slide it again. The increased friction between the surfaces in contact will make it harder to slide the blocks, showcasing the role of contact force in friction.
What factors determine the of friction between a wooden block and the surface it is resting on?
The factors that determine the friction between a wooden block and the surface it's resting on include the roughness of the surfaces in contact, the weight of the block, and the materials involved. Friction is also influenced by the normal force acting on the block, which is the force exerted by the surface perpendicular to the contact area.
What surface would have the largest frictional force to resist the motion of a wooden block?
A rough surface with a lot of friction, like sandpaper or a rubber surface, would create the largest frictional force to resist the motion of a wooden block. Smooth surfaces have less friction and would not resist the motion as much.
Which is the force that stops motion?
An opposing force: 1. Air resistance, especially if the item is airborne, such as a parachute 2. Friction, especially on a surface such as a wooden block on a table
Do wooden blocks float in water?
Yes, wooden blocks typically float in water because wood is less dense than water. This means that the buoyant force acting on the wooden block is greater than its weight, causing it to float.
A wooden block is in such perfect contact with the bottom of a water tank that there is no water beneath it. Is there a buoyant force on the block?
No. In fact, it's a question of density not of buoyancy. As it is less dense than the water, the water will sink below the block.
Is a wooden block a simple machine?
A wooden block itself is not considered a simple machine. Simple machines are devices that help to make work easier by multiplying or changing the direction of a force. Examples of simple machines include inclined planes, levers, pulleys, and screws.
What force is needed to slide a wooden block having a mass of 300 slugs moving across a floor if the friction is 0.80?
