In a spring gum having spring constant 100 `N//m` a small ball of mass 0.1 kg is put in its barrel by compressing the spring through 0.05 m
(a) Find the velocity of the ball when the spring is released.
(b) Where should a box be placed on the ground so that the ball falls in it, if the ball leaves the gun horizontally at a height of 2m above the ground. Take `g=10 m//s^(2)`

In a spring gun having spring constant 100 N/m a small ball 'B' of mass 100 g is put in its barrel (as shown in figure) by compressing the spring through 0.05 m. There should be a box placed at a distance 'd' on the ground so that the ball falls in it. If the ball leaves the gun horizontally at a height of 2 m above the ground. The value of d is ____ m. (g = 10" m/s"^(2))

In a spring gun having spring constant 100 N/m, a small ball of mass 0.1 kg is put in its barrel by compressing the spring though 0.05 m as shown in Figure. The ball leaves the gun horizontally at a height of 2 m above the ground. Find (a) The velocity of the ball when the spring is released. (b) Where should a box be placed on the ground so that that ball falls in it. (g=10 m//s^(2))

A massless spring of length l and spring constant k is placed vertically on a table. A ball of mass m is just kept on top of the spring. The maximum velocity of the ball is
