Question

Exa 6. The sketch Illustrates a \( 0,41 \mathrm{~kg} \) block that slides from \( A \) to \( B \) along a frictionless plane. When the block reaches B it continues to slide along the horizontal plane 9C where a kinetic frictional force works in on it. As a result of the frictional force the speed decreases and the block comes to a hall at C. The kinetic energy of the block at \( A \) is 37 d and the heights of \( A \) and \( B \) are 12 m and 7 m above ground respectively. 6.1 What is the kinetic energy of the block when it reaches B ?
