Question

6. A water slide can be considered to be frictionless. The top of the slide is 4.2 m above the bottom of the slide. Riders exit the slide with a horizontal velocity. The bottom of the slide is 1.5 m above the water. A certain rider has a mass of 27 kg.

A. Sketch the situation at the top of the slide, bottom if the slide, and just before they hit the water.

B. What is their gravitational potential energy at the top of the slide, relative to the bottom of the slide and relative to the top of the water?

C. What is their kinetic energy and speed at the bottom of the slide?

D. How far do they travel horizontally from the bottom of the slide before they hit the water?

E. Does the horizontal distance traveled depend on the mass of the rider? Explain.

Answer #1

A block of mass 19.6 kg starts at rest at the top of a
frictionless ramp that makes an angle of 36.2 ^\circ ∘ below the
horizontal. After it slides without friction down the entire 2.89 m
length of the ramp, it begins to slide horizontally along a rough
concrete surface with a coefficient of kinetic friction of
\mu_kμ k = 0.503 until it slows to a complete
stop. How far does the block slide horizontally along the concrete
before...

A 52.4 kg child slides down a water slide with a velocity of 1.1
m/sec at the top. At the bottom of the slide, she is moving
horizontally, y=1.5 meters above the water. She splashes into the
water d=2 meters to the left of the bottom of the slide.1) Assuming
potential energy to be zero at the water level, what is the
mechanical energy of the child at the top of the slide? MEo=?. 2)
How high is the top...

Children slide down a frictionless water slide that ends at a
height of 1.80 m above the pool.
If a child starts from rest at point A and lands in the water at
point B, a horizontal distance L = 2.63 m from the base of
the slide, determine the height h (in m) of the water
slide.

A small block travels up a frictionless incline that is at an
angle of 30.0° above the horizontal. The block has speed 4.15 m/s
at the bottom of the incline. Assume g = 9.80 m/s2. How far up the
incline (measured parallel to the surface of the incline) does the
block travel before it starts to slide back down?

A small block travels up a frictionless incline that is at an
angle of 30.0° above the horizontal. The block has speed 1.20 m/s
at the bottom of the incline. Assume g = 9.80 m/s2. How far up the
incline (measured parallel to the surface of the incline) does the
block travel before it starts to slide back down?

At the Monterey sports center pool there is a water slide whose
top is 5.00 meters above the pool. The total length of
the slide is 15.0 meters because it ‘winds’ its way down to the
water. Since water is running down the slide, there is very little
friction (we will assume none) between the swimmers’ bathing suits
and the slide surface.
Determine the final velocity of a person at the bottom
of the slide before they enter the water....

You have a mass at the top of a frictionless 85 cm ramp that has
been raised to an angle of 30° above the horizontal. Do the
following and be sure to show your work: a. Find the speed of the
mass when it reaches the bottom of the ramp if it starts from rest.
(Hint: this can be done with either the kinematics equations or
conservation of energy.) b. Once the mass reaches the bottom of the
ramp, it...

Your company is designing a new water slide. In the initial
design, a person travels down a curved slide, ending up moving
horizontally at the bottom. There, the person grabs the bottom end
of a 16.0 m long vertical bar that is pivoted at its center and
swings out over a pool of water. When the bar has swung out as far
as it will go, the person lets go and falls down into the water.
Your task is to...

After you slide down frictionless ramp B you land on horizontal
ground. The coefficient of friction between you and the ground is
