Answer:
The total distance traveled by the comet is 225000 [km]
Explanation:
In order to determine the travel distance we must use the following kinematics equation:
x = v*t
where:
x = distance traveled [km]
v = velocity = 50000 [km/h]
t = time = 4.5 [h]
x = 50000*4.5 = 225000 [km]

My best friend lol cuz since quarantine i didn't see her
Thank you for the points
the answer is b
If a football is kicked from the ground with a speed of 16.71 m/s at an angle of 49.21 degrees, then the vertical component of the initial velocity would be 12.65 m/s
<h3>What is Velocity?</h3>
The total displacement covered by any object per unit of time is known as velocity. It depends on the magnitude as well as the direction of the moving object. The unit of velocity is meter/second.
As given in the problem A football is kicked from the ground with a speed of 16.71 m/s at an angle of 49.21 degrees
The horizontal component of the velocity is given by
Vx = Vcosθ
The vertical component of the velocity is given by
Vy = Vsinθ
As we have to find the vertical component of the velocity given that speed of 16.71 m/s at an angle of 49.21 degrees from the ground
Vy = 16.71 × sin49.21°
Vy = 12.65 m/s
Thus, the vertical component of the velocity would be 12.65 m/s
