After skiding down a snow-covered hill on an inner tube, Ashley is coasting across a level snowfield at a constant velocity of 2.7 m/s. Miranda runs after her at a velocity of 4.1 m/s and hops on the inner tube. How fast do the two of them slide across the snow together on the inner tube?

3.3 m/s

Explanation:

The question is incomplete, here is the complete question:

After skiding down a snow-covered hill on an inner tube, Ashley is coasting across a level snowfield at a constant velocity of 2.7 m/s. Miranda runs after her at a velocity of 4.1 m/s and hops on the inner tube. How fast do the two of them slide across the snow together on the inner tube? Ashley's mass is 71 kg and Miranda's is 58 kg. Ignore the mass of the inner tube and any friction between the inner tube and the snow.

SOLUTION:

mass of Ashley (Ma) = 71 kg

mass of Miranda (Mm) = 58 kg

initial velocity of Ashley (Va) = 2.7 m/s

initial velocity of Miranda (Vm) = 4.1 m/s

Find the final velocity (Vf) at which they both slide together

from the conservation of momentum, initial momentum = final momentum

Ma.Va + Mm.Vm = (Ma + Mm) . Vf

Vf = (191.7 +237.8) / (129)

Vf = 3.3 m/s

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.

um if your asking how to beat a level then that i can with that and how to fix your wii but other than that i can't u
