Explanation:
Answer:
86.4 km
Explanation:
30.0 m/s * (0.8*60*60 sec) = 86,400 m = 86.4 km
The correct answer is anthracite
Perfectly inelastic collision is type of collision during which two objects collide, stay connected and momentum is conserved. Formula used for conservation of momentum is:
In case of perfectly inelastic collision v'1 and v'2 are same.
We have following information:
m₁=3 kg
m₂=? kg
v₁=x m/s
v₂=0 m/s
v'1 = v'2 = 1/3 * v₁
Now we insert given information and solve for m₂:
3*v₁ + 0*? = 3*1/3*v₁ + m₂*1/3*v₁
3v₁ = v₁ + m₂*1/3*v₁
2v₁ = m₂*1/3*v₁
2 = m₂*1/3
m₂= 6kg
Mass of second mud ball is 6kg.
Answer:
3.89 m/s
Explanation:
If we want an average velocity for the whole race of 3.81 m/s in a 1600 m course, the course it must be completed in:
.
So, the runner already run for 5 minutes and 25 seconds, this is
.
For finishing the course, the runner has
.
Now, the distance that the runner has to cover in this time its:
Finally, the runner average velocity for the remainder will be:
