Question

A small block of mass m1= 3 kg is placed at rest on a larger block of mass m2=5 kg .The situation is given in the figure below The coefficient of friction between the two block is µ=.3 And the horizontal surface is smooth.A constant Force F is applied on the block Find out the following (a) Find the value of limiting friction between the two blocks
(b) What is the maximum acceleration by which the upper block can move
(c) What is the maximum value of F at which both the block move together
(d) if F=20 N,what is the acceleration of each block and what frictional force is acting between the block
(e) What is the normal contact force between the blocks
(f) what is the normal contact force between the larger block and the smooth surface
(g) if F=40 N,what is the acceleration of each block and what frictional force is acting between the block
(h) If the force is applied to the upper block,what will be the minimum force required so that there is relative motion between the block Given g=10 m/sec2​

Answer 1

Explanation:

A small block of mass m1= 3 kg is placed at rest on a larger block of mass m2=5 kg .The situation is given in the figure below The coefficient of friction between the two block is µ=.3 And the horizontal surface is smooth.A constant Force F is applied on the block Find out the following (a) Find the value of limiting friction between the two blocks

(b) What is the maximum acceleration by which the upper block can move

(c) What is the maximum value of F at which both the block move together

(d) if F=20 N,what is the acceleration of each block and what frictional force is acting between the block

(e) What is the normal contact force between the blocks

(f) what is the normal contact force between the larger block and the smooth surface

(g) if F=40 N,what is the acceleration of each block and what frictional force is acting between the block

(h) If the force is applied to the upper block,what will be the minimum force required so that there is relative motion between the block Given g=10 m/sec2
