Answer:
This is an example of Inelastic colission
Explanation:
Step one:
given:
mass of moose m1 = 620 kg
mass of train m2= 10,000kg
Initial velocity of moose u1= 0 m/s
Initial velocity of train v1 = 10m/s
combined velocity of the system is given as v
Applying the conservation of momentum equation we have
m1u1+ m2u1= (m1+m2)V
substitutting we have
620*0+10000*10= (620+10000)V
100000= 10620V
divide both sides by 10620
V = 100000/10620
V=9.41m/s
The velocity of the moose after impact is 9.41m/s
elasticity stretches and can also return to it's normal size ..
Answer:
b. Icy objects that form a tail as they come close to the Sun
Explanation:
Acording to NASA comets are cosmic snowballs made out of frozen gases, rock and dust, they usually are the size of a small town and contain water and organic compounds due to the collisions with Earth and other planets. When its orbit brings it close to the sun, it heats up, spewding dust and gases forming a tail that streches away from the sun, they also have a glowing head that is larger than most planets.
<em>Considering this information we can conclude that the correct answer is b. Icy objects that form a tail as they come close to the Sun.</em>
I hope you find this information useful and interesting! Good luck!
