6b: impulse is change in momentum. Change in momentum p=m[v(final)-v(initial). Final velocity is zero and initial velocity is the one you calculated before impact: -15.7 since it’s going down. Now plug in numbers and you get 78.5 in the upward direction.
6c: change in momentum p=Ft. we already calculated change in momentum. So plug it into equation and solve for t. 78.5/655= 0.119 s
Apply the same idea for question 7. Hope this helped
Answer:
The mass of the asteroids is 0.000334896182184 times the mass of the Earth.
39929.4542466 m
Explanation:
Total mass of the asteroids
= Mass of Earth =
The ratio is
The mass of the asteroids is 0.000334896182184 times the mass of the Earth.
Volume is given by
The diameter is 39929.4542466 m
Evaporation - Heating
Condensation - Cooling
Freezing - Cooling
Melting - Heating
Sublimation - Heating
Deposition - Cooling
Average acceleration = (change in speed) / (time for the change)
In this case . . .
Average acceleration = (speed at the end - speed at the beginning)/10sec.
We can't be any more specific without knowing the difference
between the beginning speed and the ending speed.
