A crate push along the floor with velocity v slides a distance d after the pushing force is removed. If the mass of the crate is doubled but the initial velocity is not changed, what distance does the crate slide before stopping? Explain. If the initial velocity of the crate is double to 2v but the mass is not changed, what distance does the crate slide before stoppingexplain

1) It is friction that provides the force for a car to accelerate, so for high-performance cars the factor that limits acceleration isn't the engine; it's the tires. Part A For typical rubber-on-concrete friction, what is the shortest time in which a car could accelerate from 0 to 70 mph? Suppose that ?s=1.00, ?k=0.80, and ?r=0.02. 2.) The forces in (Figure 1) are acting on a 1.0 kg object. What is ax, the x-component of the object's acceleration? 3.)A crate...

Just asking help with Part I
A factory worker pushes a 30.0 kg crate a distance of 4.40 m along a level floor by pushing downward at an angle of 28.0° below the horizontal. The coefficient of kinetic friction between the crate and floor is 0.260. The Crate is Pushed with Increasing Speed Now assume that, instead of the previous situation, the worker pushes harder (without changing the direction of his push), so that the crate moves with increasing speed....

A crate whose mass is 22.5 kg is being pushed along a floor. There is an opposing horizontal force equal to 70.0 N. The pushing force is 125 N, but it is being applied at an angle of 35.0 degrees above the horizontal. The crate is initially at rest. Determine the following: a.) the acceleration of the crate b.) its velocity after 4.00s c.) its displacement after 4.00s d.) the normal contact force

A factory worker pushes a crate of mass 32.0 kg a distance of 4.20 m along a level floor at constant velocity by pushing horizontally on it. The coefficient of kinetic friction between the crate and floor is 0.25. What magnitude of force must the worker apply? Express your answer using two significant figures. F = N Part B How much work is done on the crate by this force? Express your answer using two significant figures. W = J ...

A block of wood of mass m = 1kg is pushed with an initial velocity of 1m/s down a ramp that makes an angle of 30 degrees with the horizontal. The coefficient of kinetic friction is 0.6. How far along the ramp does it slide before coming to rest?
A. A crate of mass 66.8 kg rests on a level surface, with a coefficient of kinetic friction 1.49. You push on the crate with an applied force of 1,178. What is the magnitude of the crate's acceler...
A. A crate of mass 66.8 kg rests on a level surface, with a coefficient of kinetic friction 1.49. You push on the crate with an applied force of 1,178. What is the magnitude of the crate's acceleration as it slides? Part A answer: 3.0327 m/s^2 B. Take the same crate of mass 66.8 kg and the same coefficient of kinetic friction 1.49, but now place the crate on an inclined surface, slanted at some angle above the horizontal. Now...

A box of mass m starts sliding across a horizontal table with some initial speed. It slides distance d before coming to rest. The coefficient of kinetic friction between the table and the box is μk. Use Newton’s laws and kinematics equations to find the initial velocity of the box. Express your answer in terms of the given parameters. Solve the same problem using work and energy theorem. Do these two approaches give the same answer? What assumptions did you...
