Figure shows a light, inextensible string attached to a cart that can slide along a frictionless horizontal rail aligned along an `x` axis. The left end of the string is pulled over a pulley, of negligible mass and friction and fixed at height `h = 3m` from the ground level. The cart slides from`x_(1) = 3 sqrt(3) m` to `x _(2) = 4 m` and during to move, tension in the string is kept constant `50 N`. Find change in kinetic energy of the cart in joules. `(Use sqrt(3) = 1.7)` in form of `10 x n`, where `n=`

Figure shows a light, inextensible string attached to a cart, which can slide along a frictionless horizontal rail aligned along the x axis. The left end of the string is pulled over a pulley of negligible mass and friction and fixed at height h=3m from the ground level. The cart slides from x_1=3sqrt3m to x_2=4m and during the move, tension in the string is kept constant at 50N . Find the change in kinetic energy of the cart in joules. (Use sqrt3=1.3 )
