Q1. A weight with a mass of 57 kg is suspended from a point near the right hand end of a uniform boom with a mass of 60 kg. To support a uniform boom a cable runs from this same point to a wall (left hand vertical coordinate) and by a pivot on the same wall at an elevation of 3m. (Max is 8.5m, so left side of triangle is 6.5, bottom is 8, and hypotenuse is T). Compute the tension in the cable. The acceleration of gravity is 9.8.

Q2. Batteries are rated in terms of ampere-hours (A h). For example, a battery that can produce the current of 3.00 A for 5.00 h is rated at 15.00 A h.

What is the total energy stored in an 8.0-V battery rated at 49.0 A h?
