Answer #1

Part 1) A 1.0 kg block is pushed 2.0 m at a constant velocity up
a vertical wall by a constant force applied at an angle of 29.0 ◦
with the horizontal, as shown in the figure. The acceleration of
gravity is 9.81 m/s 2. Drawing not to scale. If the coefficient of
kinetic friction between the block and the wall is 0.20, find a)
the work done by the force on the block. Answer in units of J.

A
block is pushed up a frictionless 30 incline by an applied force
as shown. If F = 25 N and M = 3.0 kg, what is the magnitude of the
resulting acceleration of the block? What is the magnitude of the
normal force exerted by the surface on the block?

A block of mass M = 5.80 kg, at rest on a horizontal
frictionless table, is attached to a rigid support by a spring of
constant k = 6250 N/m. A bullet of mass m = 8.30 g and velocity of
magnitude 570 m/s strikes and is embedded in the block (the
figure). Assuming the compression of the spring is negligible until
the bullet is embedded, determine (a) the speed of the block
immediately after the collision and (b) the...

An 8.5-kg block is pushed along a horizontal rough surface by a
40-N force inclined at 20° with the horizontal. The coefficient of
friction between the surface and block is 0.35. If the block has an
initial velocity of 3.6 m/s and the force does 200 J of work on the
block, find:
(a) The total distance moved by the block.
(b) The final velocity of the block.

A 6.20 kg block is pushed 9.50 m up a smooth 36.0 ∘inclined

A 16.3 kg block is dragged over a rough, horizontal surface by a
constant force of 184 N acting at an angle of angle 34.9 ? above
the horizontal. The block is displaced 44 m and the coefficient of
kinetic friction is 0.131. 16.3 kg µ = 0.131 184 N 34.9 ? Find the
work done by the 184 N force. The acceleration of gravity is 9.8
m/s 2 . Answer in units of J. 005 (part 2 of 5)...

A block of mass 0.630 kg is pushed against a horizontal spring
of negligible mass until the spring is compressed a distance x. The
force constant of the spring is 450 N/m. When it is released, the
block travels along a frictionless, horizontal surface to point
circled A, the bottom of a vertical circular track of radius R =
1.00 m, and continues to move up the track. The speed of the block
at the bottom of the track is...
