A particle \(P\) has mass 5 kg .
The particle is pulled along a rough horizontal plane by a horizontal force of magnitude 28 N .
The only resistance to motion is a frictional force of magnitude \(F\) newtons, as shown in Figure 1.
- Find the magnitude of the normal reaction of the plane on \(P\)
The particle is accelerating along the plane at \(1.4 \mathrm {~m} \mathrm {~s} ^ { - 2 }\)
- Find the value of \(F\)
The coefficient of friction between \(P\) and the plane is \(\mu\)
- Find the value of \(\mu\), giving your answer to 2 significant figures.
