a block(500N) is being pulled along a surface having coefficients of kinetic and staic friction of 0.45 and 0.5 respectively..draw a free body diagram of the block and find the minimum force that can be applied to the block at an angle 15¢X below the surface to keep the block moving once it has started to move.

assuming the surface is horizontal.
pulling force horizonatl=mu*(mg+force*sinAngle)
Force*cosAngle=mu*(mg+force*sinAngle)
solve for Force.
pulling force horizonatl=mu*(mg+force*sinAngle)
Force*cosAngle=mu*(mg+force*sinAngle)
solve for Force.
