Here's how to solve this problem: a) Calculate the acceleration of the car and the caravan Step 1: Calculate the total mass of the system. The car and caravan move together, so their masses combine. M_total = m_car + m_caravan M_total = 2100\, kg + 900\, kg M_total = 3000\, kg Step 2: Convert the engine force to Newtons. The force is given in kilonewtons (kN), so convert it to Newtons (N). F_engine = 14\, kN = 14 × 1000\, N F_engine = 14000\, N Step 3: Apply Newton's second law to find the acceleration. Using the formula F = ma, where F is the net force and m is the total mass. F_engine = M_total × a 14000\, N = 3000\, kg × a a = 14000\, N3000\, kg a = (14)/(3)\, m/s^2 a ≈ 4.67\, m/s^2 The acceleration of the car and caravan is 4.67 m/s^2. b) Find the tension in the link between the car and caravan Step 4: Consider the forces acting on the caravan. The only horizontal force acting on the caravan is the tension (T) from the link, pulling it forward. Using Newton's second law for the caravan: T = m_caravan × a. T = 900\, kg × (14)/(3)\, m/s^2 T = 300 × 14\, N T = 4200\, N The tension in the link is 4200 N. Send me the next one 📸
