A 27 kg crate rests on a floor. A horizontal pulling force of 110 N is needed to move the crate with a constant velocity. What is the coefficient of kinetic friction between the crate and the floor?
A dockworker loading crates on a ship finds that a 25-kg crate, intially at rest on a horizontal surface, requires a 72-N horizontal force to set it in motion. However, after the crate is in motion, a horizontal force of 50 N is required to keep it moving with a constant speed. Find the coefficients of static and kinetic friction between crate and floor. static friction kinetic friction
A crate of toys (25 kg) is at rest on a rough horizontal surface. The coefficients of static and kinetic friction (respectively) are 0.5 and 0.2. What minimum force is required to cause the crate to move? Assuming this force is maintained once the crate begins moving, with what acceleration does the crate move?
A crate of 37.2-kg tools rests on a horizontal floor. You exert a gradually increasing horizontal push on it and observe that the crate just begins to move when your force exceeds 322 N . After that you must reduce your push to 240 N to keep it moving at a steady 29.1 cm/s . A.What is the coefficient of static friction between the crate and the floor? B.What push must you exert to give it an acceleration of 1.11...
Suppose you have to move a heavy crate of weight 875 N by sliding it along a horizontal concrete floor. You push the crate to the right with a horizontal force of magnitude 300 N, but friction prevents the crate from sliding. Part A Draw a free-body diagram of the crate. Part B What is the magnitude Fp of the minimum force you need to exert on the crate to make it start sliding along the floor? Let the coefficient...
Side 7. A 10.0 kg block is at rest on a rough horizontal surface. A force of F - 50.0N @ 35° is applied to the vie block, as shown below. The coefficients of static and kinetic friction between the block and the horizontal surface are: Hs = 0.55 and thk = 0.35. Will the block move? If not, explain why not. If so, determine its acceleration. Your answer must include a free-body diagram. (Hint: compare the horizontal component of...
A dockworker loading crates on a ship finds that a 20-kg crate, initially at rest on a horizontal surface, requires a 73-N horizontal force to set it in motion. However, after the crate is in motion, a horizontal force of 51 N is required to keep it moving with a constant speed. Find the coefficients of static and kinetic friction between crate and floor.
The 75-kg man pushes on the 150-kg crate with a horizontal force F. The coefficients of static and kinetic friction between the crate and the surface are μs = 0.3 and μk = 0.1, and the coefficient of static friction between the man's shoes and the surface is μ′s = 0.8. What is the greatest acceleration the man can give the crate if the man's acceleration is zero at this instant? I keep getting 1.96 but it says answer is...
If you push with a horizontal 650-N force to a 90-kg crate initially at resting on the floor, what must acceleration be? The static and kinetic energy coefficient of friction are us- 0.4, uk= 0.25 respectively.
A 39 kg crate sits on a horizontal floor. The coefficients of static and kinetic friction between the crate and floor are 0.6 and 0.4, respectively. Use a coordinate system with +y pointing upwards. a) How much force do you need to apply to get the crate sliding along the floor? [ , , ] N b) If the crate is moving with a speed of [0.8, 0, 0] m/s, what force is it experiencing due to friction as it slides? [ , , ] N...
