Question 7 (8 marks) A 2.00 kg block is pulled up a rough 30 incline by a 25 .0 N force. The coefcient of friction between incline and block is 0.20. a) Draw a free-body diagram for the block. b) Determine the magnitude of the frictional force. c) Determine the magnitude of the acceleration of the block. d) How long will it take the force to pull the block 6.5 m up the incline, starting from rest at the bottom? a) Free-body diagram: b) Magnitude of friction: c) Magnitude of acceleration
