1. a) A 5.0kg block is pulled horizontally by an unknown force F. If the coefficient of static friction between the block and the surface is 0.40, find the unknown value of the force F to start the block moving b) A 5.0kg block is pulled by an unknown inclined force F. If the coefficient of static friction between the block and the surface is 0.40, find the unknown value of the force Fto start the block moving. The force F is inclined 30° from the horizontal. 2.
