After an avalanche, a huge block of stone sliddown a mount and landed in the middle of a road. People in the nearby town had a very difficult time moving it out of the road. The block of stone is difficult to move because A.it has a high amount of momentum B.has balanced forces acting on it C.it has high amount of inertia D.has unbalanced forces acting on it
It is C, it has much mass, therefore much inertia.
B.has balanced forces acting on it Since the stone has stopped moving it has no momentum or inertia. The only force acting on it is gravity pushing down which is balanced by the ground pushing up
-_- it has inertia, inertia is a property of matter, it has direct correlation with mass. It loses its momentum since it is sitting still but its mass has not changed.
so is it C or B?
It's C
