physics help please

A block of mass 418 g is pushed against the spring (located on the left-hand side of the track) and compresses the spring a distance 4.6 cm from its equilibrium position (as shown in the figure below). The block starts from rest, is accelerated by the compressed spring, and slides across a frictionless horizontal track (as shown in the figure below). It leaves the track horizontally, flies through the air, and subsequently strikes the ground. The acceleration of gravity is 9.81 m/s 2 .


-What is the spring constant? Answer in units of N/m.

-What is the speed v of the block when it leaves the track?

-What is the total speed of the block when it hits the ground?

The figure must show more than you are telling us, like for instance the distance the block lands from the end of the track, the height of the track, or other information.
