Question

A block of mass equals 4 kg is sliding down on a rough inclined surface

making an angle 300

from horizontal. (assume the acceleration due to gravity g =

10 m/s2

)

a) label all the force acting on the block.

b) calculate the force of fraction fk if the coefficient of kinetic friction is 0.3.

c) find the net force on the block​

Answer 1

Answer:

a.) refer the diagram

b.) frictional force = 6√3 N

c.) net force = 9.607 N

Answer 2

Answer:

angle of inclination is 30 degree or 300 degree....
