Question

A 1.55-kg block is launched by a spring and slides along a ramp
as shown. The spring has a spring constant of 1180 N/m and is
compressed a distance, x, before being released. The block slides
up a frictionless ramp of height, H=0.550 m, above where the block
leaves the spring. At the top of the ramp it flies horizontally off
the ramp. Just before leaving the ramp, the kinetic energy of the
block is 8.54 J. After leaving the ramp, the block lands on a ledge
a height, h=0.330 m, below where it leaves the ramp. Ignore air
resistance. The figure is NOT drawn to scale.

What is the velocity of the block just as it leaves the return?

What is the distance, x, that the spring was compressed from equilibrium when launching the block?

How much time elapses between when the block leaves the ramp and it hits the ledge?

1. A 2 kg block is on a ramp, and slides down the ramp. The ramp
has angle 30 degrees with
respect to the ground and moves the block at a constant
velocity. The block has a
displacement vector with a magnitude of 6 m. What is the work
done on the block by thefrictional force?
2. A 0.2 kg block is on a ramp. The ramp has an angle of 30
degrees with respect to the ground. The block...

block 1 of mass m1 slides from rest along a
frictionless ramp from an unknown height h and then
collides with stationary block 2, which has mass m2 =
3m1 . The collision is an elastic one. After the
collision, block 2 slides into a friction-filled region where the
coefficient of kinetic friction is 0.5 and comes to a stop through
a distance d = 10 m in that region. What is the height
h?

A.Your mass m=11 kg block slides down a frictionless ramp having
angle theta=0.51 radians to the horizontal. After sliding down the
ramp a distance L=16 m the block encounters a spring of spring
constant k=551 N/m. The spring is parallel to the ramp. Use g=9.74
m/s/s for the acceleration of gravity.
Calculate the maximum compression of the spring, in meters.

An 8.70-kg block slides with an initial speed of 1.80 m/s down a
ramp inclined at an angle of 25.3 ∘ with the horizontal. The
coefficient of kinetic friction between the block and the ramp is
0.87. Use energy conservation to find the distance the block slides
before coming to rest.

A 2.0 kg wood block is launched up a wooden ramp that is

A
1-kg block slides along frictionless surface XY with a velocity of
v = 10 m/s. It then moves along a surface YZ with length 10 m, and
uk = 0.2 until hitting an undeformed spring whose k = 1000 N/m.
What is the block’s velocity just before it hits the
spring?

After leaving the spring, will the block reach surface
XY?
If yes, compute for the velocity of the block...

A block of mass m = 4.5 kg is attached to a spring with
spring constant k = 610 N/m. It is initially at rest on an
inclined plane that is at an angle of θ = 29° with respect
to the horizontal, and the coefficient of kinetic friction between
the block and the plane is μk = 0.13. In the
initial position, where the spring is compressed by a distance of
d = 0.19 m, the mass is at...

A block (4 kg) starts from rest and slides down

A block with a mass m = 2.12 kg is pushed into an ideal spring
whose spring constant is k = 3810 N/m. The spring is compressed x =
0.069 m and released. After losing contact with the spring, the
block slides a distance of d = 2.07 m across the floor before
coming to rest.

between the block and the floor using the symbols given in the
problem statement...

A block with mass m = 14 kg rests on a frictionless table and is
accelerated by a spring with spring constant k = 4399 N/m after
being compressed a distance x1 = 0.468 m from the
spring’s unstretched length. The floor is frictionless except for a
rough patch a distance d = 2 m long. For this rough path, the
coefficient of friction is μk = 0.48.
