Damon thank you so much for your help. It's great to have the answer and it makes total sense now. You must be a teacher... Thank you thank you thank you
You are welcome. Yes, I was a teacher many years ago.
I'm having trouble with the one about why the image's important to U.S History :(
I also need big help with question 6 :( taking a test grade 8
To solve this problem, we can apply the principles of linear motion using the formula:
v = Δx / Δt
Where:
v is the velocity
Δx is the displacement
Δt is the time
Let's break down the problem into two parts: the pitcher's throw and the ball being hit back to the pitcher.
1. Pitcher's Throw:
Given:
- Distance from batter to pitcher (Δx): 18.5 m
- Velocity of the pitch (v): 40 m/s
We need to find the time it takes for the pitch to reach the batter. Rearranging the formula, we have:
Δt = Δx / v
Δt = 18.5 m / 40 m/s
Δt ≈ 0.463 s
So it takes approximately 0.463 seconds for the pitch to reach the batter.
2. Ball Hit Back to the Pitcher:
Given:
- Initial velocity of the ball (v_initial): 50 m/s
- Time of contact (Δt): 0.03 s
We need to find the displacement of the ball when it travels back to the pitcher. Rearranging the formula, we have:
Δx = v * Δt
Δx = 50 m/s * 0.03 s
Δx = 1.5 m
Therefore, the ball travels 1.5 meters when hit back to the pitcher.
To summarize:
- The pitch takes approximately 0.463 seconds to reach the batter.
- When the ball is hit back to the pitcher, it travels 1.5 meters.
Note: In this simplified scenario, we assume a linear path for the ball, neglecting factors such as gravity and air resistance, which would affect the actual motion of a baseball.
acceleration is change in velocity over change in time
[40 - (-50)] / .03
= 90/.03
= 3000 m/s^2
