The $10-kg$ triangular block is held at rest on a smooth inclined plane by a stop$-$block $A.$ The $10-$gram bullet is traveling at $300\frac{m}{s}$ when it hits the $10-kg$ block and becomes embedded in it$.$ Assume the motion of the combined block $($i$.$e$.,$ triangular block & the bullet$)$ is ONLY on the $x-$axis.

a$)$ Draw the free body diagram showing all forces acting on the combined block after

it starts moving along the $x-$axis.

b$)$

Determing all forces acting on the combined block

c$)$ Determine initial speed that the combined block starts moving up the inclined plane.

c$)$ Determine the distance the combined block slides up the inclined plane before momentarily stopping.
