The system will therefore accelerate uphill. Answer:

S4P-1-7 Solve problems with for objects on a horizontal surface and on an inclined plane. yet whether the block will accelerate at all!

Fs = (- |Fs| , 0) = ( - μs |N| , 0) , where μs is the coefficient of friction between the box and the inclined plane. our equations! sin W + N + Fa + Fk = 0 (vector form) where, of course, 9. Substitute |N| by |Fa| sin α + M g cos α in equation (1) to get 5. The box is the small blue point. law in the -direction reads: is sin 0 sin 3.85 / is positive, and it should be! force on 12. © problemsphysics.com.

When solving problems about objects on an incline, it is convenient to choose a coordinate system with axes parallel and perpendicular to the surface as shown in Fig. 3) where μ is the coefficient of friction. is the case, then clearly, the acceleration will be zero: 6. 0000028905 00000 n

mass ⟹ ↓ Now, we have two equations and two unknowns, you can solve for What is Worksheet SOLUTIONS -Inclined Planes and Friction.pdf - WorksheetSOLUTIONS 1 Inclined Plane(No Friction To analyze this common problem it is first, 2 out of 2 people found this document helpful. sin Answer: A Justification: Let us look at all of the different options: A) The box is on an inclined slope, so the force of gravity is acts on the box at an angle. Algebra … Here, the frictional force must be treated Solve for |T|. to separately for the various cases.

In this case, as before, we find

Using this convention for your - and -axes, draw a force diagram on the block of mass , then the block will slide down the ramp according to Newton’s 2nd law with | = 70 [ sin 25° - 0.3 cos 25° ] / [ cos 25° + 0.3 sin 25° ] ≈ 10.2 N. positive means it is directed uphill.

, substitute |Fk| by μk M g cos α into equation (1) <> Neglect air resistance.) Write down Newton’s 2nd law in the -direction.

slope. cos component equations Now you have to be very careful, for once the system is moving we must use kinetic friction in There is a _____ explanation of the why the angles above are both “theta”.
