1.
A boy at
A
throws a ball 45
o
from the horizontal such that it strikes the slope at
B
.
Determine the speed
at which the ball is thrown and the time of flight.
2.
The inclined plane supports block
A
which has a weight of 10 lb.
The tension,
T, exerted on the rope is 9 lbs.
If the coefficient of kinetic friction between the
block and the plane is
μ
k
= 0.1, determine the acceleration along the plane for
the block.
Assume the block starts from rest.
3.
Using a forked rod, a smooth cylinder
P
, having
a mass of 2 kg, is forced to move along the
vertical slotted path r = (0.6
θ
) m, where
is in
radians.
If the forked rod has a constant angular
speed of
±
=0.2 rad/s, determine the magnitude
of the velocity and acceleration of the cylinder at
the instant
=
π
rad.
Assume the cylinder is
in contact with only one edge of the rod and slot
at any instant.
