A block of mass m = 2.0 kg is sitting stationary on a table. A horizontal force of magnitude F = 5.0 N is applied to the block, as shown. The coefficient of static friction is µS = 0.7, and the coefficient of kinetic friction is µK = 0.5. To the nearest 0.1 N, what is the magnitude of the force of friction between the block and the table?

A block of mass m lies on a horizontal table. The coefficient of static friction between the block and the table is ?s. The coefficient of kinetic friction is ?k, with ?k<?s. 1)If the block is at rest (and the only forces acting on the block are the force due to gravity and the normal force from the table), what is the magnitude of the force due to friction? 2)Suppose you want to move the block, but you want to...

Question 7 A 0.73 kg block is placed on a horizontal surface with a coefficient of kinetic friction of 0.122. The block is pressed against a spring that has a spring constant of 683 N/m until it has compressed the spring by 13.7 cm. When the block is allowed to move freely, the spring pushes the block 10 cm along the horizontal surface at which point it encounters an upward slope with an angle of 29.0°. This slope has the...

A block of mass 3.5 kg is sitting on a frictionless ramp with a
spring at the bottom that has a spring constant of 435 N/m (refer
to the figure). The angle of the ramp with respect to the
horizontal is 29°. show answer Incorrect Answer 33% Part (a) The
block, starting from rest, slides down the ramp a distance 52 cm
before hitting the spring. How far, in centimeters, is the spring
compressed as the block comes to momentary...

To understand kinetic and static friction. A block of mass m lies on a horizontal table. The coefficient of static friction between the block and the table is μs. The coefficient of kinetic friction is μk, with μk<μs. a- Suppose you want to move the block, but you want to push it with the least force possible to get it moving. With what force F must you be pushing the block just before the block begins to move? Express the...

A block of mass m = 3.5 kg is
on an inclined plane with a coefficient of friction
μ1 = 0.31, at an
initial height h = 0.53 m above
the ground. The plane is inclined at an angle θ =
54°. The block is then compressed against
a spring a distance Δx = 0.11 m
from its equilibrium point (the spring has a spring constant of
k1 = 39 N/m) and
released. At the bottom of the inclined plane...

A hand pushes a 4 kg block along a table from point A to point C as shown in the figure below. The table has been prepared so that the left half of the table (from A to B) is frictionless. The right half (from B to C) has a non-zero coefficient of friction equal to u. The hand pushes the block the full distance from A to C using a constant force of 7 N. The block starts off...
