Yuliya22 [10]
<h2>Mercury, Neptune, and Jupiter </h2>

Explanation:

  • Mercury has the largest semimajor axis that is 5.791 x 107 in km.
  • Mercury is the planet with the fastest speed, which has an average orbital speed around the sun for about 47.87 km/s.
  • Neptune has the longest orbital speed around the sun of any planet in the Solar System which is equivalent to 164.8 years (or 60,182 Earth days)
  • Jupiter has the largest eccentricity.

Hence, the answer is Mercury, Neptune, and Jupiter respectively.

A stone thrown off a bridge 10m above a river has an initial velocity of 8ms at an angle of 25 degrees above the horizontal. Wha
Darina [25.2K]

Explanation:

It is given that,

Height above which the stone was thrown, h = 10 m

Initial velocity of the stone, u = 8 m/s

Angle above the horizontal, \theta=25^{\circ}

The horizontal component of velocity is, u_x=v\ cos\theta=8\ cos(25)=7.25\ m/s

The vertical component of velocity is, u_y=v\ sin\theta=8\ cos(25)=3.38\ m/s

Let t is the time of flight in vertical motion. The second equation of motion is :

h=u_yt-\dfrac{1}{2}gt^2

10=3.38t-\dfrac{1}{2}\times 9.8t^2      

t = 0.34 seconds

Let s is the range of the stone. It can be calculated as :

s=u_x\ cos\theta \times t

s=7.25\times 0.34

s = 2.46 meters

So, the range of the stone is 2.46 meters. Hence, this is the required solution.
