The bob of a pendulum of length 2 m lies at P. When it reaches Q it loses 10% of its total energy due to air resistance. For this event, which of the following is a correct statement.

The bob of a pendulum was released from a horizontal position. The length of the pendulum is 10m. If it dissipates 10% of its initial energy against air resistance, the speed with which the bob arrives at the lowest point is : [Use, g : 10 ms^(–2) ]

A simple pendulum of length 1 oscillates aboμt the mean position as shown in the figure. If the total energy of the pendulum is E, the velocity of the pendulum bob of mass m at point P is:

The bob of a pendulum is released from a horizontal position. If the length of pendulum is 2 m, what is the speed with which the bob arrives at the lower most point. Assume that 10% of its energy is dissipated against air resistance. (Take g = 10 m s^(-2) )

The bob of a pendulum is released from a horizontal position. If the length of pendulum is 2 m, what is the speed with which the bob arrives at the lower most point. Assume that 10% of its energy is dissipated against air resistance. (Take g = 10 m s^(-2) )

A runner weighing 60 kg raises the CG of his body by 0.25 m during each step of 1 min length. If he runs for 6 km and there is loss of 10% of the energy due to friction of air etc. What is the total energy required by him from his intake of food ?

The string of a pendulum is 2.0m long. The bob is pulled sideways so that the string becomes horizontal and then the bob is released. What is the speed with which the bob arrives at the lowest point ? Assume theat 10% of initial energy is dissipated against air resistance. Take g=10m//s^(2)
