Q1. A block with a mass of 20 g is pulled at a constant speed across a horizontal tabletop with a spring scale. The scale reads 65.3N. Calculate the coefficient of kinetic friction.

Q2. A curve of radius 50 m is banked for the design speed of 100 km/h. If the coefficient of static friction is 0.60 (wet pavement), at what range of speeds can a car safely create the curve?
