A block of mass 10kg is pushed up on a smooth incline plane of inclination 30^(@) , so that it has acceleration 2m//s^(2) . The applied force is

Two bodies of massless string passing over a frictionless pulley. The acceleration of the system is (g=9.8m//s^(2))

A block of mass 10 kg accelerates uniformly from rest to a speed of 2 m/s in 20 sec. The average power developed in time interval of 0 to 20 sec is

A block of mass m_1 = 4kg lying on a plane inclined at an angle of 30^(@) , is connected to another freely suspended block of mass m_2 = 6kg with the help of a string passing over a smooth pulley as shown in the figure. The acceleration of each block is (g = 10 m/ s^2 )

A block of mass 3 kg is pulled up on a smooth incline of angle 37^@ with the horizontal. If the block moves with an acceleration 2(m)//(s^2) , find the power delivered by the pulling force at time 5 s after the motion starts. What is the average power delivered during the 5.0 s after the motion starts?

Two blocks of masses 2 kg and 4 kg tied to a string passing over a frictionless pulley. What will be the magnitude of acceleration of the masses, when they are allowed to move freely?
