Q. A box is sliding down an incline tilted at an angle 14.0° above horizontal. The box is sliding down the incline at a speed of 1.70 m/s. The coefficient of kinetic friction between the box and the incline is 0.380. How far does the box slide down the incline before coming to rest?

Q. There are 8 Iron balls of look alike and a weighing machine. Out of the 8 balls 7 are of equal weight and 1 is lower weight. Question is that how can you measure the lowest weight ball out of the 8 balls in 2 iteration means you have to weight those balls only twice using weigning machine and select the lowest weight ball?
