In a children-park an inclined plane is constructed with an angle of incline 45o in the middle part (figure 6-E1). Find the acceleration of a boy eliding on It if
the friction coefficient between the cloth
of the boy and the incline is 0.6 and g = 10 m/s2.


let the mass of the boy= m

Angle of inclination θ= 45o


Coefficient of friction = 0.6


According to the figure given below,





The force due to which boy is sliding down is






Acceleration of the boy a= = = m/s2
