A ship of mass `3xx10^7kg` initially at rest, is pulled by a force of `5xx10^5N` through a distance of 3m. Assuming that the resistance due to water is negligible, the speed of the ship is

A ship of mass 3xx10^(2)kg initially at rest is pulled by a force of 5xx10^(4) N through a distance of 3m. Neglecting frcition, the speed of the ship at this moment is:

If a ship of mass 4 xx 10 ^( 7 ) kg initially at rest is pulled by a force of 5 xx 10 ^ ( 4 ) N through a distance of 4 m, then the speed of the ship will be (resistance due to water is negligible )

A body of mass 3 kg at rest is acted upon by a force and the body moves through a distance 20 m in 5 s. Force on the body is

. The mass of a ship is 2 xx 10^7 kg. On applying a force of 25 xx 10^5 N, it is displaced through 25 m. The speed of ship is

In a shotput event an athlete throws the shotput of mass 10 kg with an initial speed of 1 ms^(-1) at 45^@ from a height 1.5 m above ground. Assuming air resistance to be negligible and acceleration due to gravity to be 10 ms^(-2) , the kinetic energy of the shotput when it just reaches the ground will be

In a shotput event, an athlete throws the shotput of mass 10kg with an initial speed of 1ms^(-1) at 45^(@) from a heigth 1.5m above ground. Assuming air resistance to be negligible and acceleration due to gravity to be 10ms^(-2) , the kinetic energy of the shotput when it just reaches the ground will be

In a shotput event an athlete throws the shotput of mass 20 kg with an initial speed of 2 m s^(-1) at 45^@ from height 3 m above ground. Assuming air resistance to be negligible and acceleration due to gravity to be 10 m s^(-2) , the kinetic energy of the shotput when it just reaches the ground will be
