Hello,
A soccer ball is kicked at an angle of 30° to the playing surface. Calculate the throwing time, throwing distance, and maximum throwing height if the initial speed is 100 km/h and air resistance is negligible.
I have solved the problem and am not sure if it is correct:
The second task is: Draw his throwing trajectory. Calculate four additional points. Can anyone give me some tips on how to do this? Thanks in advance.

Loading...Hello, I have a question regarding 3b. I understand the approach, but why can you simply subtract A1 and A2? But why should the area of f(x) be the same size as that of g(x).
Could an object be launched into space using a slingshot/catapult with tremendous energy? I'm thinking of a railgun or similar magnet-powered catapult. Would that be an alternative to rocket launch?
Hey, I don’t know how to calculate this (Figure 6). I look forward to answers with calculation method
So it says: Since v' is it is derived, giving a But the derived v', i.e., a, stands for ACCELERATION. The solutions say it's SPEED, which can't be true because we derived it, so it's ACCELERATION, right?
Hello, can someone explain to me using example 4 how the degree and points were calculated? Thanks
Looks good so far! To sketch this, you know it’s a twisted parabola. You already have the impact point (x=68,03) peak value at 9.62m and half of the impact point.
Simply put a few different t in the formulas for s_y and s_x (important, in both the same t values) and then you get the points for the respective time (s_x is the x axis and s_y is the y axis). The t should be selected between 0 and the time of impact.
The formula for s_y should be in the boardwork; something like that
No guarantee of accuracy!
I watch in my old school stuff had this two years ago now I have to calculate speed for scavenger and the length of bent sheets xdddd
Edited: I was looking but remembered that I burned my old school tool I’m sorry 😅😂😂
Okay, but thanks
No problem maybe I can help next time
