AP Physics 1 Name: ……………………..
Unit 2 - Classwork - Questions on Newton’s Laws …………/25
1. A mass of 2.00 kg rests on a rough horizontal table. The maximum frictional force between the mass
and the table is 12N. The block is attached to a hanging mass by a string that goes over a smooth
pulley. What is the largest mass that can hang in this way without forcing the block to slide?
(2 marks)
2. A mass of 5.00 kg hangs attached to three strings as shown in the figure. Find the tension in each
string?
(4 marks)
