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

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.

would be false hope this out
