7. A heavy chandelier with mass 125 kg is hung by two chains from the ceiling of a concert hall as shown in the figure below with 01=37° and 02-64°. Assuming that the chains are massless, what are the tensions FT1 and Frz in the two chains? 02 FT2 FTi X.

Two blocks connected by a light string are being pulled across a frictionless horizontal tabletop by a hanging 16.7-N weight T, 2 A (block C). Block A has a mass of 2.00 kg. The mass of block B T, В is only 1.00 kg. The strings remain taut at all times. Assuming the pulley is massless and frictionless, what are the values of the tensions T1 and T,? C T = N T2 = 36.3 N

A stack of books of total mass 3.13kg is placed on a table as seen in A. It is then placed on a sturdy piece of wood inclined at an angle of 15 degrees (refer to B). What is the ratio of the normal force in A to the normal force in B?

Two carts on a low friction air-track are connected by an unstretched spring.   Cart 1 has an inertia of 1.5 kg while cart 2 has an inertia of 2.5 kg.   The spring has a spring constant of 10 N/m and negligible inertia.   You push cart 1 in the direction of the cart 2 with a constant force of 5.0 N.   (a) What is the acceleration of the centre of mass of the cart-spring system?          (b) What is the acceleration of each cart the instant you begin to push?
