\fFor Problems 3-6: Your mother asked you to pull a 50-kg sack of rice to be placed on the kitchen floor based on the illustration below. You are to pull this sack of rice at a distance of 10 meters along the horizontal. F = 500 N H& = 0.2375. What is the work done by you pulling the sack of rice with 500-N force? a. -5,000 J b. 5,000 J c. -1,161 ] d. 1,161 ] 6. How much is the total work done on the system? a. OJ b. 5,000 J c. -1.161 ] d. None of the above7. Which of the following statement/s is/are always true about two objects' kinetic energies? I Both objects have the same kinetic energy if the two objects' masses and velocities are equal. II Both objects have the same kinetic energy even if object 1's mass is only 1/4 of object 2, and object 1's velocity is twice of object 2. III Both objects have the same kinetic energy even if object 1's mass is only 1/6 of object 2, and object 1's velocity is thrice of object 2. a. I only b. I and II only c. I, II, and III only d. None of the above 8. Which of the following statement/s is/are best describe/s the relationship between work and acceleration on a block travelling to the right? I If the block travels at constant velocity, the total work done is positive. II If a force causes the block to accelerate, the total work done is negative. III If a force causes the block to decelerate, the total work done is positive. a. I only b. I and II only c. I, II, and III only d. None of the above
