Apendulum consists of a stone with mass m swinging on a string of length l and negligible mass. the stone has a speed of v0 when it passes its lowest point. (a) write an expression for the speed of the stone when the string is at some angle θ with the vertical. (b) what is the greatest angle with the vertical that the string will reach during the stone's motion? (c) if the potential energy of the pendulum-earth system is taken to be zero at the stone's lowest point, what is the total mechanical energy of the system? state all your answers in terms of the given variables and g.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
