A 6.53-kg block initially at rest is pulled to the right along a
horizontal surface by a constant force of 125 N applied at an angle
θ above the horizontal. The coefficient of kinetic friction between
the block and the horizontal surface is 0.150. At what angle θ
above the horizontal surface should the force be applied to achieve
the largest possible speed after the block has moved 5.00 m to the
right?

he block in the figure lies on a horizontal frictionless
surface, and the spring constant is 50 N/m. Initially, the spring
is at its relaxed length and the block is stationary at position x
= 0. Then an applied force with a constant magnitude of 4.0 N pulls
the block in the positive direction of the x axis, stretching the
spring until the block stops. When that stopping point is reached,
what are (a) the position of the block, (b)...

A 3.0-kg block sliding on a frictionless horizontal surface is
accelerated by a compressed spring. If the 200 N/m spring is
initially compressed 10 cm, determine (a) the potential energy
stored in the spring. As the block leaves the spring, find (b) the
kinetic energy of the block, and (c) the velocity of the block.

Let's imagine a block on a sheet of ice, with negligible
friction. The block has a mass of 5.00 kg. The block is currently
moving to the right at 3.00 m/s. Let's say a rope is attached to
this block, and it pulls horizontally on the block, also to the
right, with a force of 12.0 N. With this force applied, the block
moves a distance of 3.00 m to the right. How fast is the block
moving at the...

A 28 kg block on a horizontal surface is attached to a
horizontal spring of spring constant k = 4.8 kN/m. The block is
pulled to the right so that the spring is stretched 7.2 cm beyond
its relaxed length, and the block is then released from rest. The
frictional force between the sliding block and the surface has a
magnitude of 37 N. (a) What is the kinetic energy of the block when
it has moved 1.6 cm from...

A 1.8 kg block at rest on a table is attached to a spring of
spring constant 1.1 N/m that is parallel to the table top. The
spring is initially unstretched. A constant 27.9 N force is
applied, causing the spring to stretch.

equilibrium if
