Q1. A staging that weighs 440 N supports two painters, one 110 N and the other 460 N. The reading in the left scale is Ft = 800 N. What is the reading Fr, in the right hand scale?

Q2. A bullet of mass 5.0 g is fired horizontally into a 2.7 kg wooden block at rest on a horizontal surface. The coefficient of kinetic friction between block and surface is 0.20. The bullet stops in the block that slides straight ahead for 1.2 m (without rotation).

What is the speed of the block immediately after bullet stops relative to it?
