- A small block of mass 490 g rests close to the left wall of a box of equal mass. Length of the box is 40 cm. The box is placed on a horizontal floor Jubricated with oil. Force of viscous friction of the lubricating oil is given by equation F = -kü, where k = 0.5 kg/s andü is velocity of the box relative to the floor. There is no friction between the block and the floor of the box. If the block is given a velocity 10 m/s towards the right, how many times will the block collide with walls of the box and how far will the box move? Ana! 49¢9.8 thon the
