A block with mass M = 3 kg is moving on a flat surface with constant speed v1 = 12 m/s. A bullet with mass m = 0,1 kg is shot at an angle = 20 with respect to the direction of the movement of the block. The speed of the bullet is v2 = 400 m/s. At what angle and with what speed does the block move after it is hit by the bullet that remains stuck inside the block? Draw a sketch. How long does it take for the block to stop moving if the friction coefficient between the block and the surface is kt = 0,2?
