Two packing crates of masses 10.0 kg and 5.0 kg are connected by a light string that passes over a frictionless pulley . The 10.0 kg crate lies on a smooth inclined plane. Determine the inclined plane angle , that would lead to the 2 crates in equilibrium (no acceleration) . What is the tension in the string? If the system needs to be adjusted and 5kg crate is moving downward with an acceleration with an acceleration of 1.0 m/s², determine the angle of the inclined plane and the tension in the string. [take the acceleration for 5.0 kg is going down]

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)
