The average speed is 52km
Answer:
3.59 m/s
Explanation:
We are given that
Mass of lineman,m=85 kg
Mass of receiver,m'=90 kg
Speed of receiver,v'=5.8 m/s
Speed of lineman,v=4.1 m/s
We have to find the their velocity immediately after the tackle.
Initial momentum,
According to law of conservation of momentum
Initial momentum=Final momentum=
<span>F x L = W x X whereW=weight is total load = 80, L is length from fulcrum which is the unknown and what we are solving for. x= length we know. and F equals 50 force we know. So (W*X)/F=LL equals 64</span>
Answer:
Asteroids are objects made of clay and silicate that orbit the sun but are too small to be considered planets.
Most asteroids revolve around the sun in an orbit between those of Mars and Jupiter.
They form a wide band called the Asteroid belt.
Other asteroids have orbits that cross Earth’s orbit. These asteroids are called Earth-crossers.
Asteroids probably consist of matter that never agglomerated into a planet when the solar system was forming.
The comet’s core is composed of ice and dust.
Comets heat up and begin to change from a solid to a gas as they approach the sun.
The matter surrounding a comet’s core is vaporized and forms a very bright halo of ice or dust not sure, and an enormous cloud of dust or gasses not sure envelopes the head of the comet.
