Farm Power

Subtopic: Tractor Braking

Question Statement:

A tractor weighing 30 kN travels at 20 km/h (5.56 m/s) on dry asphalt. When brakes are applied, it stops in a distance of 4.5 m. The average braking deceleration in m/s$^2$ is:

Answer Key:

3.43

Step-by-Step Solution & Explanation

Using kinematic equation $v^2 = u^2 - 2 a s \implies 0 = (5.556)^2 - 2 a (4.5) \implies 9 a = 30.864 \implies a = \frac{30.864}{9} \approx 3.43\text{ m/s}^2$.
