You're on a roll — Step 1: Calculate the weight of the bag of cement. The mass of the cement bag is 50 \, kg and the acceleration due to gravity g = 10 \, m/s^2. The weight of the cement bag is given by W_cement = m_cement × g. W_cement = 50 \, kg × 10 \, m/s^2 = 500 \, N Step 2: Calculate the total downward force exerted on the ground. The total downward force is the sum of the boy's weight and the cement bag's weight. Boy's weight W_boy = 78 \, N. Total downward force F_total = W_boy + W_cement. F_total = 78 \, N + 500 \, N = 578 \, N Step 3: Determine the reaction of the ground. According to Newton's third law, the reaction force from the ground is equal in magnitude and opposite in direction to the total downward force exerted on it. Therefore, the reaction of the ground on the bag of cement and the boy is 578 \, N. The reaction of the ground is 578 \, N. Drop the next question!
