A conveyor belt is moving at a constant speed of 2m/s . A box is grenty dropped on it. Th ecoefficient of friction between them is μ=0.5 . The distance that the box will move relative to belt before coming to rest on it taking g=10ms−2 is:

 A conveyor belt is moving at a constant speed of  2m/s

 A box is grenty dropped on it. Th ecoefficient of friction between them is μ=0.5${\displaystyle \mu =0.5}$ . The distance that the box will move relative to belt before coming to rest on it taking g=10ms−2${\displaystyle g=10m{s}^{-2}}$ is:

sol. friction force = μN = μmg

accelration = F/m  = μg

a = 0.5 * 10 = 5unit

v2 = u2 + 2as

0= 4-10S
