Pushing a Block and a Wedge 0 points possible (ungraded) In the following problem, you are asked to: i) Define the system and the environment: Identify which objects - the environment - interact with the object of interest - the system. Justify your choice of system: would a different choice also work? If not, why not? If so, why is the choice you made better? ii) Describe the interactions and the resulting forces: Identify the forces exerted on the object of interest by the other objects. iii) Draw the free body diagram of the object: Make sure that each force arrow is labeled with two subscripts - who is exerting the force and on whom is the force being exerted. The length of the arrows should represent qualitatively the magnitude of the force. a) c) M m 0 a F M m 0 A block of mass m rests on a frictionless wedge which has a mass M and whose surface makes an angle to the horizontal as Calculator

A crate, which has a weight of W, is placed on an inclination. The force P is applied to prevent the crate from sliding down the inclination. a) Determine the minimum required force P, if the coefficient of static friction is u31. b) Determine the friction force (in magnitude) acting at the bottom of the crate if the force P=P1 and the coefficient of statie friction is µs1. c) Determine the minimum required force P, if the coefficient of static friction is u32. Use W=450 N, a=35°, us1=0.4, Hs2=0.75 and P=115 N. The minimum required force P in N is (if the coefficient of static friction is µs1) (round to the nearest integer): N The magnitude of friction in N is (if the force P-P, and the coefficient of static friction is u1) (round to the nearest integer): N The minimum required force P in N is (if the coefficient of static friction is µs2) (round to the nearest integer): N
