Q1. A loudspeaker of mass 21.0 {rm kg} is suspended the distance of h = 2.40 {rm m} below the ceiling by two cables that make equal angles with the ceiling. Each cable has a length of l = 3.90 {rm m}.

What is the tension T in each of cables?

Use 9.80 {rm m/s} ^ 2 for the magnitude of the acceleration by reason of gravity.

Q2. A golf ball with an initial angle of 34? lands exactly 240m down the range on a level course. The acceleration of gravity is 9.8 m/s2.

a) Neglecting air friction, what initial speed would achieve this result?

b) Using speed determined in item (a), find the maximum height reached by the ball.
