machine in an ice fatory is capable of exering 3 x 10*2n of force to pull a large block of ice up slope......?

Question

The blovk weighs 1.22 x 10*4 N. Assuming there is no friction what is the maximum angle that the slope can make with the horizontal if the machine is to able to complete the task?

Answer 1

The force exerted by the machine F must balance the the force due to gravity along the wedge W sin(A) =mg sin(A)

F=Wsin(A)

A=arcSin( F/W)
A= arcSin( 3 E+2/1.22E+4)
A=1.4 deg
