The[m2]-kg block shown sits on top of a[m1]-kg ramp,which is being pushed by an external forceP.Thecoefficients of static and kinetic frictions between the rampand block are[μs]and 0.2 respectively. The ramp is onrollers and we can assume its contact with the ground isfrictionless. ForcePis always applied in the direction shown.(a) Calculate the minimum forcePrequired to keep the block from sliding on the ramp.(b) Calculate the maximum forcePthat can be applied before the block slides on the ramp.

Question

The[m2]-kg block shown sits on top of a[m1]-kg ramp,which is being pushed by an external forceP.Thecoefficients of static and kinetic frictions between the rampand block are[μs]and 0.2 respectively. The ramp is onrollers and we can assume its contact with the ground isfrictionless. ForcePis always applied in the direction shown.(a) Calculate the minimum forcePrequired to keep the block from sliding on the ramp.(b) Calculate the maximum forcePthat can be applied before the block slides on the ramp.

Hints: • When P = ON (static equilibrium), the block slides since u, < tan (20°). Values The system is accelerating. Avoid using a rotated coordinate system. т — 250 т2 — 100 Us = 0.25
