speed of block at the bottom of the slope

1. The problem statement, all variables and given/known data
A block is placed on a slope at an angle of 38.2. The height of the inclined plane is h = 1.880m. The block has a mass of m = 7.80kg. if the coefficient of kinetic friction is =0.111 and the coefficient of static friction = 0.162.

a) what is the speed of the block at the bottom of the slope?

b) what is the magnitude of the net force on the block halfway down the slope?

2. Relevant equations

3. The attempt at a solution
