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

When released the block shal have a kinetic eneigy of 1/8

B

The initial horizontal velocity of the block is `sqrt(5//2)ms^(-1)`

C

The block shall reach the ground in `sqrt(2//5)` second

D

The block shall hit the ground at a horizontal distance of 1 metre from the free end of the spring.
