Answer :

The velocity of the block is given as


Given


The spring with a spring constant of k, at a height of h forming at an angle of 37o


Formula Used


Using the conservation of static and dynamic energy such as spring energy and kinetic energy, we have the conservation equation as



where


m is the mass of the object, v is the velocity, k is the spring constant and x is the elongation distance.


Explanation


To find the speed of the block moved from the resting position is given as





Due to 37o angle forming the height is written in terms of





Placing the height of the horizontal plane and block as




Hence, the velocity of the block is given as
