Question

solve each block and use the answer in the next bock to climb to the top
? ×10=
​

Answer 1

Answer:

you have given no block

Step-by-step explanation:

please add all blocks

Answer 2

Answer:

Step-by-step explanation:

Frictional force , f=μR=mgsin37  

∘

 

Where , μ is the coefficient of friction  

Net force acting on the block =mgsin37  

∘

−f  

=mgsin37  

∘

−μmgcos37  

∘

 

=mg(sin37  

∘

−μcos37  

∘

)  

At equilibrium the work done by the block is equal to the potential energy of the spring i.e.,  

mg(sin37  

∘

−μcos37  

∘

)x=(1/2)kx

1×9.8(sin37  

∘

−μcos37  

∘

)=(1/2)×100×(0.1)  

0.602−μ×0.799=0.510  

∴μ=0.092/0.799=0.115
