Acceleration of gravity and baseball problem

Click For Summary

Homework Help Overview

The discussion revolves around a physics problem involving the motion of a baseball hit into the air, specifically focusing on the relationship between distance, time, and height under the influence of gravity. The acceleration due to gravity is given as 9.8 m/s², and participants are exploring how to determine the height the ball reaches based on the time it remains airborne.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss various equations that could relate height to distance and time, questioning the relevance of distance in the context of the problem. Some suggest that the height is determined by gravitational acceleration and time alone, while others express uncertainty about which equation to use.

Discussion Status

The conversation is ongoing, with some participants providing hints and guidance without revealing complete solutions. There is a recognition that multiple interpretations of the problem exist, particularly regarding the relationship between distance and height. Participants are encouraged to apply their understanding of motion equations.

Contextual Notes

One participant notes the importance of understanding basic equations of motion, indicating that the problem may be part of a homework assignment with potential scoring implications for incorrect answers. There is also a mention of a follow-up question regarding the angle of the baseball's trajectory, adding complexity to the discussion.

during a baseball game, a batter hits a popup to a fielder a distance of D m aways. the acceleration of gravity is 9.8m/s^2. if the ball reamins in the air for T seconds, how high does it rise.
1. h=D/4T
2.h=1/8gT^2
3.h=4D/T
4.h=2D/T
5.h=D/T
6.h=2gT^3
7.h=D/(2T)

Key:2

the motion in the direction of gravity is not ralated with D, h=0.5gt^2.
t is half of T, for T is up and down, and t is up or down
 
?

so which one is the answer?
 
Well, the answer is unrelated to D, so that eliminates 5 of the options.
 
?

yea but which one cause if i get it wrong it deducts from my score. n my score is bad enough
 
Neverland's answer should give you a clue, but you should really be able to work it out by yourself.
The question is asking you to show your knowledge of basic equations of motion.
Do you know these ?
 
thanks

i figured it out but now they are asking for the angle and they give you the distance and time.

is the distance half of at the maximum height?
