Answer:
Explanation:
given,
location of the ball ⟨7,0,−8⟩
initial velocity of the ball ⟨-11,19,−5⟩
time = 0.4 s
speed of the ball = ?
using Momentum Principle
change in momentum = Force x time
Net force acting in this case will be equal to force due to gravity because air resistance is negligible.
F_net = F_g = ⟨0 ,-9.8 m , 0⟩
now,
hence, the velocity of the ball 0.4 s after being kicked is equal to
Answer:
There are several kinds of plants who grow and thrive near volcanic locations. For example coffee, grape vines, moss and the rare Hawaiian argyroxiphium, or "silversword." These plants grow and survive using the nutrients from the ashes of the volcanic eruptions along with cooled lava.
Mosses and Lichens form a protective layer over the land which helps it to retain water inside it, rather than drying out which is the case in volcanic sites. Therefore, the retained water helps the land to form and become appropriate for other plants to grow as well.

The flow of electrical charge per unit time
Answer:
When mass increases, kinetic energy also increases. Changing mass doesn’t affect his speed on a given ramp.
