Aworker pulls horizontally on a crate across a rough horizontal surface, causing it to move forward with constant velocity. force a is the force exerted by the worker and force b is the force of friction due to the surface. what is the relationship between a and b?
a > b
a = b
a< b
it will not slow down, but continue moving at constant velocity.

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)
