Block with mass of m is shot from the point A with initial velocity of Vo=5m/s.
Starting from point C, block experience
friction force and comes to rest at point D.
If the magnitude of the friction force
equals to mechanical energy of the block
at the point where the block is 6m above
from the ground, find the distance CD.
(h1=15m, h2=6m, g=10m/s?)

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.

Sorry i don’t know what to do

Im like heat is absorbed i like think

President amoto wanted to develop the industry in south gamara by stabilizing the country and increasing its gbp.   south gamara is a poor country and it is less developed.   and because the countrymen of south gamara is poor people lacks capital to make new business and this is what president gamara want to do for his country. to have a new business for his people and to increase the gbp.american care, compare, free country, government health, industry jobs , life and the president himself.
