  1. Forces Questions FA on an angle

  2. The coefficient of friction between a 10kg bag of leaves and a wet lawn is 0.20. The applied force pulling the bag is 40N [40o above the horizontal]. • What is the normal force? • What is the force of friction? • What is the net force and acceleration of the bag?

  3. To drag a 4kg backpack to class, a student pulls the bag with a force of 10N [35o above horizontal]. a. What is the normal force? b. If the bag moves at a constant speed, what is the force of friction? c. What is the coefficient of friction?

  4. To push a 12kg shopping cart, the applied force is 20N [30o below the horizontal]. a. What is the normal force? b. If the cart accelerates at 0.5m/s2, what is the force of friction? c. What is the coefficient of friction?

  5. While tobogganing, I give Meg (24kg) a push to get her moving. The applied force is 40N [25o below horizontal]. The coefficient of friction is 0.1. a. What is her acceleration? b. How fast is she moving if she starts from rest and I push for 2s?

  6. When I pull a 3kg desk with a force of 25N [45o above the horizontal] the desk accelerates from rest to 1m/s in a distance of 0.40cm. What is the coefficient of friction?
