The sliding frictional force
between a 4 kg box and the floor is 15 N. It is pushed
across the floor with a constant force such that it accelerates
at 0.8 ms-2.
If this same force calculated is applied to the box which is now placed on a frictionless floor what is the new acceleration produced?
A 8.2 ms-2
B 16.2 ms-2
C 4.6 ms-2
D 2.3 ms-2
please tell me the answer, also has everybody received the mock papers for second level?
