QUESTION 5 A wооden blоck, mаss 1.59 kg, rests on the side of а tаble that is 1.2 m above the ground. A bullet, weighing 0.01 kg, moving horizontally at an unknown velocity, hits the wooden block on the table. After impact, the bullet hits the block, which then falls to the ground and hits the ground at a velocity of 5 m.s-1. Right click on the following blue button to open ALL THE IMAGES for QUESTION 5, in a new tab. 5.1 Use the principle of conservation of mechanical energy to calculate the magnitude of the velocity at which the block leaves the table. (5) 5.2 If friction between the block and the table top is taken into account, how will it affect the final velocity of the block-bullet system? Write only INCREASE, DECREASE or STAY THE SAME. (1) A crate with a mass of 40 kg must be loaded on a truck by sliding it upwards over an inflexible steel beam from point X (on the ground) to point Y (at the level of the truck). The warehouse foreman uses the principle of conserving mechanical energy to solve the problem without thinking about the frictional force. He calculates that he can get the crate against the steel beam to point Y (which is 0.8 m above the ground) by pushing it at X at an initial speed of 4 m.s-1 and then releasing it. Please make use of Diagram 2, Question 5 to assist in answering the following questions. 5.3 Point Y is 0.8 m above the ground. Use the principle of conservation of mechanical energy to calculate the kinetic energy of the crate should friction not cause any energy to be lost. (5) 5.4 Draw a free force diagram, with labels, showing all the forces acting on the crate between point X and point Z. (3) 5.5 Calculate the magnitude of the frictional force on the crate as it moves upwards . (6) [20]
