wall
A block of mass m = 2 kg is
held stationary against a wall
by applying a horizontal
m
F-
force F on it as shown in Fig.
5.41. If the coefficient of fric-
tion between the block and
the wall is u = 0.25, find the
minimum value of F required
to hold the block against the
wall. Take g = 10 ms.

1O C A cart for hauling ore out of a gold mine has a mass of 439 kg , including its load. The cart runs along a straight stretch of B Track track that climbs a shallow 4.75° incline. A donkey, which is Rope trudging along and to the side of the track, has the unenviable job of pulling the cart up the slope with a 441 N force for a distance of 185 m by means of a rope that is parallel to the slope but makes an angle of 14.5° with the track. A „Track incline Model the rolling resistance of the cart as though it were Horizontal ground sliding on the track with a coefficient of friction of 0.0163.
