Neil and Gus are having a competition to see who can launch a marble highest in the air using their own spring. Neil has a firm

spring (kNeil = 50.8 N/m), but it can be compressed only a maximum of yNeil, max = 14.0 cm. Gus’s spring is less firm than Neil’s (kGus = 12.7 N/m), but its maximum compression is greater (yGus, max = 27.0 cm). Given that the mass of the marble is 4.5 g and ignoring the effects of air resistance, who can launch the marble the highest and what is the winning height? Assume the marble starts from the same height, in both cases when the springs are at maximum compression.

Answer:

Neil (221.2m) can throw the marble higher than Gus (205.4 m)

Explanation:

Let's use the law of conservation of energy, the selected points are, the - --    maximum compression of the spring

        Eo = Ke = ½ k x2

Maximum height

        Ef = U = mgh

As there is no rubbing

         E = Ef

         ½ k x² = ½ m g h

         h = k x² / m

Let's calculate for each person

Neil

         x1 = 14.0 cm (1m / 100cm) = 0.140 m

         m = 4.5 gr (1 kg / 1000 g) = 4.5 10⁻³ kg

         h1 = 50.8 0.140 2 /4.5 10⁻³

         h1 = 221.2 m

Gus

        x2 = 27.0 cm = 0.270 m

        h2 = 12.7 0.270 2 /4.5 10⁻³

        h2 = 205.4 m

We see that Neil (221.2m) can throw the marble higher than Gus (205.4 m)

Is it possible for an object to be going 100 miles per hour but have a velocity of zero?
Lesechka [4]
It is possible for on object to be going at 100 miles per hour, but still have a velocity. This is because the object going at 100 miles per hour has speed, which is a scalar quantity, which is defined by only magnitude, but the velocity of the object can be 0, since velocity is a vector quantity which is defined by both magnitude and direction.

Since this object only has magnitude and no direction (which is not given), then the velocity can be 0

1)Atmospheric decreases with the increase with in height?​
lina2011 [118]

Answer:

Explanation:

pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.
