A baseball player hits the ball at a speed of 20.1 m/s and an angle of 30 degrees. What is the baseball's horizontal velocity? 1m/s
What is the baseball's vertical velocity? 2m/s
How long does it take the baseball to get 28m in front of home plate? 3 seconds
Horizontal? what is 20.1*cos30?
vertical? 20.1*sin30
so putting your work here, with idiotic senseless answers is a waste of your time, and ours. It would have been smarter to no put answers as 1,2,3
You are wasting our and your time. I hope you do not try this with your physics teacher.
ummmmmmmmmmmm who the heck are you???
im asking a simple physics question if you have a problem then you can take it somewhere else darling:)

To calculate the horizontal velocity of the baseball, we need to decompose the initial velocity into its horizontal and vertical components. The horizontal velocity remains constant throughout the motion, so it is equal to the initial velocity times the cosine of the launch angle.
Horizontal velocity = Initial velocity * cos(angle)
In this case, the initial velocity is 20.1 m/s and the launch angle is 30 degrees. So, the horizontal velocity is:
Horizontal velocity = 20.1 m/s * cos(30 degrees) = 17.39 m/s
Thus, the baseball's horizontal velocity is 17.39 m/s.
To calculate the vertical velocity of the baseball, we use the same logic. The vertical velocity changes as the baseball moves due to gravity, but initially, it is equal to the initial velocity times the sine of the launch angle.
Vertical velocity = Initial velocity * sin(angle)
Using the given values, the vertical velocity is:
Vertical velocity = 20.1 m/s * sin(30 degrees) = 10.05 m/s
Therefore, the baseball's vertical velocity is 10.05 m/s.
To determine how long it takes the baseball to travel 28m in front of home plate, we need to consider only the horizontal motion because the vertical motion is not affected by the horizontal distance.
We can use the formula:
Distance = Velocity * Time
In this case, the distance is 28m, and the horizontal velocity is 17.39 m/s (as calculated earlier). By rearranging the formula, we can solve for time:
Time = Distance / Velocity
Substituting the given values, we get:
Time = 28m / 17.39 m/s ≈ 1.61 seconds
Therefore, it takes approximately 1.61 seconds for the baseball to travel 28m in front of home plate.
