A tractor with a pulling force of 15kN on the hook imparts an acceleration of 0.5m ^ 2 to the trailer. What is the weight of the trailer?
To find the value of the mass of the trailer, we will use the formula: F = m * a (Newton’s second law), from where we express: m = F / a.
Variables: F – traction force of the tractor used on the hook (F = 15 kN = 15 * 10 ^ 3 N); a is the acceleration acquired by the trailer (a = 0.5 m / s2).
Calculation: m = F / a = 15 * 10 ^ 3 / 0.5 = 30 * 10 ^ 3 kg = 30 tons.
Answer: The trailer weighs 30 tons.
