Aprojectile is launched from a point on level ground with initial speed 7.1 miles/hour and initial angle of 6 degrees above the horizontal. air resistance may be ignored and normal earth gravity is present. calculate the final value of the horizontal component of velocity in m/s just prior to the projectile striking the ground. [note: don't forget to convert units as needed.] g

Final value of horizontal component velocity will be -3.11 m/sec        

Explanation:

We have given initial velocity of the projectile u = 7.1 miles/hour

We know that 1 miles = 1609 m

Angle of projection

And 1 hour = 3600 sec

So

Now initial value of horizontal component

Now final value of horizontal component

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate
