Question

Say you push on a 5 kg block with a force of
*F*_{a} = 20 N, at a 45° angle downward. The
coefficient of kinetic friction between the block and the ground is
?_{k} = 0.3. The coefficient of static friction is unknown,
but it is known that ?_{s} > 0.3. The block is moving
with initial velocity to the right (the +*x* direction),
*v*_{0} = 2 m/s.

a) What is the magnitude of the force of friction on the box, in Newtons?

b) What is the x component of the box's acceleration, in
m/s^{2}?

Answer #1

Mary applies a force of 75 N to push a box with an acceleration
of 0.43 m/s2. When she increases the pushing force to 81 N, the
box's acceleration changes to 0.63 m/s2. There is a constant
friction force present between the floor and the box. (a) What is
the mass of the box? kg (b) What is the coefficient of kinetic
friction between the floor and the box?
(a) What is the mass of the box?
_________kg
(b) What...

This force can either push the block upward at a constant
velocity or allow it to slide downward at a constant velocity. The
magnitude of the force is different in the two cases, while the
directional angle θ is the same. Kinetic friction exists between
the block and the wall, and the coefficient of kinetic friction is
0.310. The weight of the block is 47.0 N, and the directional angle
for the force F → is θ = 31.0°. Determine...

A
5.00 kg block sits on the floor at rest. You pull on a rope upwards
at an angle. The coefficient of static friction is 0.400 and the
coefficient of kinetic friction is 0.300. When you pull upwards
with a force of 20.0 N at an angle of 35.0°, what is the force of
friction on the box? What is the acceleration of the box?

The 5 kg block is receiving a horizontal force of 50 N on the inclined side. The angle between the block and the slope is 30 degrees and the static friction coefficient is 0.3. (1) When the block goes up, what is the acceleration? (2) If the initial speed of the block was 4m/s upward, to what height can the block go up? (3) What happens after the block goes up to its highest height?

A block with mass m1 = 8.8 kg is on an incline with
an angle θ = 27° with respect to the horizontal. For the first
question there is no friction between the incline and the
block.
1. When there is no friction, what is the magnitude of the
acceleration of the block?
2. Now with friction, the acceleration is measured to be only a
= 3.52 m/s2. What is the coefficient of kinetic friction
between the incline and the...

A block with mass m1 = 8.6 kg is on an incline with
an angle θ = 29° with respect to the horizontal. For the first
question there is no friction between the incline and the
block.
1)When there is no friction, what is the magnitude of the
acceleration of the block?
2)Now with friction, the acceleration is measured to be only a =
3.42 m/s2. What is the coefficient of kinetic friction
between the incline and the block?
3)To...

A horizontal force of 60.0 N is applied to a 3.00 kg block as
the block slides a distance of 0.500 m up a ramp. The ramp is
inclined at an angle of 30.0◦ and the coefficient of kinetic
friction between the ramp and the block is 0.600. If the block is
initially at rest, how fast is it moving at the end of the
displacement? Please make answer very detailed

3-A 1.0 kg block slides down an inclined plane of 39
0 from the horizontal. If the
block starts from rest and hits the bottom in 5.1 s,
what is the speed of the block, in the unit m/s, at the bottom of
the incline? Assume a frictionless plane.
4-A bus negotiates a turn of radius 103 m while traveling at a
speed of 92 km/h. If slipping just begins at this speed, what is
the coefficient of static friction between the...

A 5 kg block rests on a flat surface with a coefficient of
