Complete question
A cannon with a muzzle velocity of 500. meters per second fires a cannonball at an angle of 30.° above the horizontal. What is the vertical component of the cannonball's velocity as it leaves the cannon?
A 0.0 m/s
B 250. m/s
C 433 m/s
D 500. m/s
Answer:
The correct option is C
Explanation:
From the question we are told that
The velocity is
The angle is
Generally the vertical component of the canon ball is mathematically represented as
=>
=>
-- "constant velocity" ===> acceleration is 0 .
-- acceleration=0 ===> forces are balanced
-- balanced forces ===> (friction) + (force you exert) = 0
(friction) = -(force you exert)
They have equal magnitude and opposite direction.

-- How does the thickness of a material affect insulation?
You could take a guess at the answer to each of these,
and then test to see if your guess is correct.
