Question
Two forces are applied to a
car in an effort to move it,
as shown in Figure P4.12.
(a) What is the resultant
vector of these two forces?
(b) If the car has a mass
of 3 000 kg, what accelera-
tion does it have? Ignore
friction.
A block of mass m 5 5.8 kg is
pulled up a u 5 25° incline
as in Figure P4.24 with a
force of magnitude F 5 32 N.
(a) Find the acceleration of
the block if the incline is fric-
tionless. (b) Find the accel-
eration of the block if the
coefficient of kinetic friction
between the block and incline is 0.10.
