Calculate the minimum force P required to move the crate to the right. Each of the wedges are weightless and have a 14° taper angle. Use the angle of friction method to solve. μs = 0.30, μk = 0.25 between all surfaces. Note: The angle of friction doesn’t require you to use a closed polygon method. You can just draw the resultant and then break it down into x and y components.

Ablock of mass m slides on a horizontal frictionless table with an initial speed v0 . it then compresses a spring of force constant k and is brought to rest. the acceleration of gravity is 9.8 m/s2. how much is the spring compressed x from its natural length? 1) x = v0*sqrt(k/(mg)) 2) x=v0*sqrt(m/k) 3) x=v0*((mk)/g) 4) x=v0*sqrt(k/m) 5) x=v0*(m/kg) 6) x=v0*sqrt((mg)/k) 7) x=(v0)^2/(2g) 8) x=v0*(k/(mg)) 9) x=(v0)^2/(2m) 10) x=v0*((mg)/k)
