-Your answer is partially correct. A horizontal force of magnitude 36.0 N pushes a block of mass 4.32 kg across a floor where the coefficient of kinetic friction is 0.596. (a) How much work is done by that applied force on the block-floor system when the block slides through a displacement of 4.53 m across the floor? (b) During that displacement, the thermal energy of the block increases by 44.9 J.What is the increase in thermal energy of the floor?...
A horizontal force of magnitude 35.0 N pushes a block of mass 4.00 kg across a floor where the coefficient of kinetic friction is 0.600. What is the increase in the kinetic energy of the block when the block slides through a displacement of 5.00 m across the floor?
.1. A horizontal force of 60.0 N is applied to a 3.00 kg block. The block is initially at rest and slides a distance of 0.500 m up a ramp once the horizontal force is applied. The ramp is inclined at an angle of 30.0◦ and the coefficient of kinetic friction between the ramp and the block is 0.600. (a) Use Newton’s second law and kinematics to determine how long it took for the block to slide 0.500 m up...
A block with a mass of 32.5 kg is pushed with a horizontal force of 150 N. The block moves at a constant speed across a level, rough floor a distance of 6.50 m. (a) What is the work done (in J) by the 150 N force? J (b) What is the coefficient of kinetic friction between the block and the floor?
Problem 5: A horizontal force F of magnitude 12 N is applied to a 2.0 kg block as that block slides a distance d 0.3 m up a ramp at angle e 35°. Assuming the coefficient of kinetic friction between the block and the ramp is ux 0.4, find the block's change in Kinetic Energy over the displacement d
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 factory worker pushes a 29.3 kg crate a distance of 4.1 m along a level floor at constant velocity by pushing downward at an angle of 28 ∘ below the horizontal. The coefficient of kinetic friction between the crate and floor is 0.25. 1) What magnitude of force must the worker apply to move the crate at constant velocity? 2) How much work is done on the crate by this force when the crate is pushed a distance of...
