1. A passenger bus of 16 ton is running on a highway at a velocity of 90 km/hr. Suddenly, one rear wheel got punctured and bus driver stops the bus in 10 seconds. Determine:

(i) The distance covered by bus during that time

(ii) Braking force applied by driver to stop the bus

2. A body of 12 kN is kept on a rough incline. Determine the velocity and distance covered by body in 4 seconds. Take angle of incline as 30° and coefficient of friction between the contact surfaces as 0.28.
