A ball is released from the bottom of a tank filled with water up to 2m. On reaching the top its kinetic energy is found to be 16 J. Mass of the ball is 2 kg. Ignoring the viscosity, let W_(1) be the work done by upthrust and W_(2) the work done by gravity, then (g = 10 m//s^(2))

Assertion : A ball is released from the bottom of a tank filled with a liquid. It moves upwards . In moving upwards upthrust will decrease. Reason : Density of ball is less than the density of liquid.

A wooden ball of density sigma is released from the bottom of a tank which is filled with a liquid of density rho (rho>sigma) up to a height h_(1) . The ball rises in the liquid, emerges from its surface and attains a height h_(2) in air.If viscous effects are neglected,the ratio h_(2)/h_(1) is

In taking a solid ball of rubber from the surface to the bottom of a lake of 180 m depth, reduction in the volume of the ball is 0.01 % . The density of water of the lake is 1xx10^(3) kg//m^(3) . Determine the value of the bulk modulus of elasticity of rubber . (g = 9.8 m//s^(2))

A ball is dropped from the top of an 80 m high tower After 2 s another ball is thrown downwards from the tower. Both the balls reach the ground simultaneously. The initial speed of the second ball is

A ball is released from the top of a building of height 45m at t=0 . When the ball strikes the ground, its speed becomes (2)/(3) times its original value. The time instant when the ball strikes the ground for the second time is t = ...........sec . ["Take" g=10 m//s^(2) ]
