Right Barnabas, let's go. a) Step 1: Convert the mass of the bag from grams to kilograms. m_bag = 1000 g = 1 kg Step 2: Calculate the total mass the applicant is carrying. M_total = m_applicant + m_bag M_total = 50 kg + 1 kg M_total = 51 kg Step 3: Calculate the total weight (force) exerted by the applicant and the bag. W_total = M_total × g W_total = 51 kg × 10 m/s^2 W_total = 510 N To determine if the applicant was given a job, the company would need a specific weight limit or physical requirement, which is not provided in the question. The total weight the applicant is carrying is 510 N. b) It is easier to move down stairs than climbing stairs because when moving down, gravity assists the motion. Your body's potential energy is converted into kinetic energy or dissipated, requiring less muscular effort to control the descent. When climbing stairs, you must work against gravity, expending energy to increase your potential energy and lift your body mass upwards. Send me the next one 📸
