Please solve for work done by friction force
A 3.0-kg block is dragged over a rough horizontal surface by a constant force of 16 N acting at an angle of 37degree above the horizontal as shown. The speed of the block increases from 4.0m/s to 6.0m/s in a displacement of 5.0 m. What work was done by the friction force during this displacement?

3.0 - 6.00 m ASSO 13.0-kg block is released from point A with initial speed of -2.0 m/s ( block is given a push up or down the ramp). The track is frictionless except for the portion between points B and C which has a length of 6.00 m. The block travels down the track, hits a spring of force constant 2,000 N/m, and compresses the spring 0.20 m from its equilibrium position before coming to rest momentarily. Determine the...

A constant force equal to F=3i+2j N is applied to a block which weighs 3.0 kg. The block is moved from a point <1.2,1.4,0> and eventually arrives at a position <1.9,1.1,0>. a) How much work is done by the force F given above? b) What is the change in kinetic energy of the block? c) If the block starts from 3.0 m/s what is the magnitude of its final velocity?
As shown in the figure below, a 2.25-kg block is released from rest on a ramp of height h.
As shown in the figure below, a 2.25-kg block is released from rest on a ramp of height h. When the block is released, it slides without friction to the bottom of the ramp, and then continues across a surface that is frictionless except for a rough patch of width 15.0 cm that has a coefficient of kinetic friction μk = 0.520. Find h such that the block's speed after crossing the rough patch is 4.20 m/s. An object with a...
