Question

100 N force has been applied on a 10 kg block. What is the acceleration of the block below?

Answer 1

Answer: Correct option is

B

0.98 m/sec  

2

 

 

Consider net acceleration of the slab be a limiting friction  

F  

s

​

=μmg=0.6×10×9.8=58.8N

Since 100N>58.8N

Therefore, slab will accelerate with different acceleration  

f=40a

0.4×10×9.8=40a

a=0.98m/s

Explanation:

Answer 2

Consider net acceleration of the slab be a limiting friction

F
s
​
=μmg=0.6×10×9.8=58.8N

Since 100N>58.8N

Therefore, slab will accelerate with different acceleration

f=40a

0.4×10×9.8=40a

a=0.98m/s
