Question

4. A box sits on an inclined plane without sliding. As the angle
of inclination increases, thenormal force

(a) decreases(b) increases(c) does not change(d) is directed
upward

please explain why.

Answer #1

MgSin =

As increases,
Sin increases, For
equation to hold true, N decreases, <90

MgCos = N

Similarly As increases , Cos decreases, N decreases <90

A 5 kg box sits on an inclined plane. If the coefficient of
static friction between the plane and the box is µs = 0.15. What is
the maximum angle θmax that the plane can be inclined without the
box sliding?

A box sits at the top of an inclined plane with a height of 6
meters. The plane is tilted at an angle which is just barelysteep
enough to make the box to begin sliding from rest. If the
coefficient of kinetic friction between the box and the incline is
0.34 and the coefficient of static friction between the box and the
incline is 0.6, determine the time in seconds that it will take for
the box to reach the...

A 16.1 kg box is at rest on an inclined plane. The plane makes
an angle of 39.3 with the horizontal. How much is the friction
force (in Newtons) on the plane that holds it at rest?

A box is on an inclined which has angle θ=30 degrees
with horizon. There is a box with mass M=5 kg on the inclined. The
coefficient of friction between the box and the surface of inclined
is μ=0.2 . a) If the box is kicked to move up the inclined and
start moving up with velocity V=15 m/s moving upward, how far d=?
does It move along the surface of inclined? b) How much energy Q=?
is lost while the...

A box is sliding down an incline tilted at a 11.8° angle above
horizontal. The box is initially sliding down the incline at a
speed of 1.60 m/s. The coefficient of kinetic friction between the
box and the incline is 0.390. How far does the box slide down the
incline before coming to rest?
A) .736 m
B) 1.03 m
C) .883 m
D) .589 m
E) the box does not stop. it accelerates down the plane.

In the figure, a 5.40 kg block is sent sliding up a plane
inclined at θ = 37.0° while a horizontal force
of magnitude 50.0 N acts on it. The coefficient of
kinetic friction between block and plane is 0.330. What are the
(a) magnitude and (b) direction
(up or down the plane) of the block's acceleration? The block's
initial speed is 4.30 m/s. (c) How far up the
plane does the block go? (d) When it reaches its
highest...

1a. a box of dirty money (mass m1
= 3.5 kg) on a frictionless plane inclined at angle θ1 =
37°. The box is connected via a cord of negligible mass to a box of
laundered money (mass m2 = 1.3 kg) on a
frictionless plane inclined at angle θ2 = 54°. The
pulley is frictionless and has negligible mass. What is the tension
in the cord?
1b. three blocks attached by cords that loop over frictionless
pulleys. Block B lies...

A block of weight w = 25.0 N sits on a frictionless
inclined plane, which makes an angle θ = 20.0 ∘ with
respect to the horizontal, as shown in the figure. (Figure 1)A
force of magnitude F = 8.55 N , applied parallel to the
incline, is just sufficient to pull the block up the plane at
constant speed.
Part B
What is Wg, the work done on the block by the force of
gravity w⃗ as the block moves...

A 4.08 kg box begins to slide from rest through a plane inclined
at 25.0 degrees (with respect to the horizontal) and which is 7.00
m long. The friction force between the box and the inclined plane
is 5.0 N. Determine: (a) the speed of the box when reaching the end
