Z 1,5 m X 0=30° A block A with a mass of 3,6 kg is placed against a compressed spring at point X. The block and spring is then released from rest. The block moves up a rough incline (XZ) at an angle of 30° to the horizontal. The spring constant of the spring is 450 N/m and it is compressed by 0,80 m at point X. Determine the kinetic energy (in J) of block A at point Z if the frictional force between the block and the surface is 21 N. (Give your answer to 2 significant figures.) E E E LE
