The distance between two telephone poles is 36 m. when a 1.99 kg bird lands on the telephone wire midway between the poles, the wire sags 0.118 m. the acceleration of gravity is 9.8 m/s 2 . how much tension in the wire does the bird produce? ignore the weight of the wire. answer in units of n.

1501.86 N

Explanation:

Given

Distance between Poles=36 m

Mass of bird (m)=1.99 kg

wire sag =0.118 m

angle made by wire with horizontal is given by

Let be the tensions in the wires

On resolving

thus

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .
