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))

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

A 700 g block is released from rest at height h_(0) above a vertical spring with spring constant k=450N//m and negligible mass. The block sticks to the spring and momentarily stops after compressing the spring 19.0 cm. How much work is done (a) by the block on the spring and (b) by the spring on the block ? (c) What is the value of h_(0) ? (d) If the block were released from height 2.00h_(0) above the spring, what would be the maximum compression of the spring ?

A spring gun has a spring constant of 80Ncm^(-1) . The spring is compressed 12cm by a ball of mass 15g . How much is the potential energy of the spring ? If the trigger is pulled, what will be the velocity of ball ?

The block of mass m is released when the spring was in its natrual length. Spring constant is k. Find the maximum elongation of the spring.

a block of mass 0.1 kg attached to a spring of spring constant 400 N/m pulled horizontally from x=0 to x_1 =10 mm. Find the work done by the spring force

The time period of an oscillating spring of mass 630 g and spring constant 100 N/m with a load of 1 kg is

A small block of mass 100 g is pressed again a horizontal spring fixed at one end to compress the sprign through 5.0 cm. The spring constant is 100 N/m. When released, the block moves hroizontally till it leaves the spring. Where will it hit the ground 2 m below the spring?

A ball of mass m kg hangs from a spring of spring constant k . The ball oscillates with a period of T seconds if the ball is removed, the spring is shortened( w.r.t. length in mean position) by
