Answer:
5.4kgm/s towards the hitter.
Explanation:
Given parameters:
Mass = 0.12kg
Velocity = 45m/s
Unknown:
Momentum of the baseball = ?
Solution:
To solve this problem, we must understand that the momentum of a body is the quantity of motion it possesses.
Momentum = mass x velocity
Now insert the parameters and solve;
Momentum = 0.12 x 45 = 5.4kgm/s towards the hitter.
Answer:
5.92×10⁷ J
Explanation:
We'll begin by converting 15 tons to Newton. This can be obtained as follow:
1 ton = 9806.65 N
Therefore,
15 ton = 15 ton × 9806.65 N / 1 ton
15 ton = 147099.75 N
Next, we shall convert one-quarter (¼) or 0.25 mile to metre. This can be obtained as follow:
100 mi = 160934 m
0.25 mi = 0.25 mi × 160934 / 100 mi
0.25 mi = 402.335 m
Finally, we shall determine the Workdone. This can be obtained as follow:
Force (F) = 147099.75 N
Distance (d) = 402.335 m
Workdone (Wd) =?
Wd = F × d
Wd = 147099.75 × 402.335
Wd = 5.92×10⁷ J
Thus, the Workdone is 5.92×10⁷ J

If a volcano epulses massive amounts of dust into the atmosphere, those two things will/can happen.
The events will last until the dust lays down on the earth.
