# Question: An object mass 3 0 kg slides upward on a vertical

An object (mass 3.0 kg) slides upward on a vertical wall at constant velocity when a force F of 60 N acts on it at an angle of to the horizontal.

(a) Draw the free-body diagram of the object.

(b) Using Newton’s laws find the normal force on the object.

(c) Determine the force of kinetic friction on the object.

In the apparatus shown in Fig. 4.43, and the coefficients of static and kinetic friction between m1 and the inclined plane are 0.30 and 0.20, respectively. (a) What is m2 if both masses are at rest? (b) What is m2 if both ...Two blocks (A and B) remain stuck together as they are pulled to the right by a force F = 200 N (Fig. 4.47). B is on a rough horizontal tabletop (coefficient of kinetic friction of 0.800). (a) What is the acceleration of ...(a) If an object is at rest, there must be no forces acting on it. Is this statement correct? Explain. (b) If the net force on an object is zero, can you conclude that the object is at rest? Explain. When on a jet airliner that is taking off, you feel that you are being “pushed” back into the seat. Use Newton’s first law to explain why. A student weighing 600 N crouches on a scale and suddenly springs vertically upward. Will the scale read more or less than 600 N just before the student leaves the scale?Post your question
