2. A crate is pushed horizontally at an angle of 20° across a rough surface as shown. The mass of the crate is 55 kg and the coefficient of kinetic friction M = 0.35. a) What applied force is required to keep the box moving at a constant acceleration of 3m/s2 ? b) What applied force is needed to keep the box moving at a constant speed, that is, no acceleration?

A crate sits on wooden horizontal surface (a wooden floor). The figure shows a top view of this looking down onto the crate (gravity would be acting into the page). Man one and man two apply forces F1 and F2, at angles of θ1 and θ2 respectively, with the goal of moving the crate in the x-direction. A resultant force of Fr = 31 lbs in the x-direction is required to accomplish this. All of the forces are in the...

1. An unknown mass (mı) on a rough horizontal surface is attached by a wire that passes over a massless, frictionless pulley to a 2.50kg mass (m2) as shown below. The bottom of the hanging mass is 1.50m above the floor. The system is released from rest at t-0s and the 2.50kg mass strikes the floor 0.82s later. The system is now returned to its initial position and a 1.20kg mass is placed on top of the block of mass...
