2. A block of mass 3.2 kg lying on an inclined plane is connected to a hanging rock of mass 3.2 kg by a very light cord passing over a pulley at the top of the inclined plane. Determine the acceleration of the block, given a coefficient of friction of 0.15 and an angle of elevation of the ramp of 25 degrees. (Consider the mass and friction of the pulley to be negligible).

u=13

v=30

s/t=u+1\2at

=13+431/2

=13+265.5

=278.5

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
