Afactory robot drops a 10 kg computer onto a conveyor belt running at 3.1 m/s. the materials are such that
? s = 0.50 and ? k = 0.30 between the belt and the computer. how far is the computer dragged before it is riding smoothly on the belt?
a) 0.98 m
b) 3.0 m
c) 1.6 m
d) 2.3 m

Option (c) will be correct answer that is it will go 1.6 m

Explanation:

We have given that conveyor has the velocity u = 3.1 m/sec

Mass of the robot = 10 kg

static friction coefficient  = 0.5 and kinetic friction coefficient = 0.3

Acceleration due to gravity g = 9.8

Acceleration a = kinetic friction coefficient ×g = 0.3×9.8 = 2.94

Now according to third equation of motion

Finally velocity of the conveyor will be zero

So

s = 1.6 m

So option (c) is correct option
