Question
A block of unknown mass is at rest on a rough horizontal surface. A force F is applied to the block. the graph in the figure show the acceleration of the block w.r.t. the applied force.
The mass of the block and coefficient of friction are (g = 10m/s2)
The mass of the block and coefficient of friction are (g = 10m/s2)
Options
A.2kg, 0.1
B.2kg,0.2
C.1kg. 0.1
D.Can′t be determined
Solution
Acceleration of block a = 
F - μg
Form graph ,slope
⇒ m = 2 kg and y-intercept ; - μg = - 2 ⇒ μ = 0.2
F - μgForm graph ,slope
⇒ m = 2 kg and y-intercept ; - μg = - 2 ⇒ μ = 0.2 Create a free account to view solution
