A 2.7-kg box is released on a horizontal surface with an initial speed of 2.9 ms It moves on the surface with a deceleration of 0.27 ms2 Calculate the kinetic friction force on the box?

Net force = 20-12 = 8N
Mass = 2 kg
Using F = ma, we get required a = F/m = 8/2 = 4 m/s2

How does friction generates static electricity?
because when friction builds up too much energy it is released through spraks and so.
When energy is released when friction is applied?
friction creates heat. Largely heat, which comes from the external agent energy causing the friction. Also some possible rearrangement of the atomic/molecular structure of the surface, and the energy for that also comes from the external agent.
A 210 g block is pressed against a spring of force constant 1.40 kNm until the block compresses the spring 10.0 cm The spring rests at the bottom of a ramp inclined at 60.0 to the horizontal Use e?
a system shown in figure is released from pulley from rest.pulley and spring is massless and friction is absent everywhere .the speed of 5kg when 2kg block leaves the ground is how much
Why do you get shocked when you rub wood and fur together?
When you rub wood & fur together, a heat/electric energy is released. this energy is called "friction". Friction moves so fast that the "shock" you feel is actually the energy moving to your body.
When you rub your hands together on a cold day you use friction to convert what energy?
The friction force converts mechanical energy of the body into heat energy that is released. Work done by mechanical energy=Force x displacement =Heat produced.
