A football is thrown upward at a 43 degree angle to the horizontal

AI Thread Summary
To calculate the initial speed of a football thrown at a 43-degree angle to achieve a 77.8 m pass, the kinematic equations for constant acceleration are essential. The acceleration due to gravity is 9.8 m/s², and the problem requires analyzing both vertical and horizontal components of the motion. Participants emphasize the importance of breaking down the motion into these components to apply the relevant equations effectively. Guidance is provided to encourage independent problem-solving rather than providing direct answers. Understanding these principles is crucial for solving projectile motion problems accurately.

A football is thrown upward at a(n) 43 degree angle
to the horizontal.
The acceleration of gravity is 9.8 ms^2 :
To throw a(n) 77.8 m pass, what must be
the initial speed of the ball? Answer in units
of ms.

Again, you need to show some work. Are you familiar with the kinematic equations for constant acceleration? Do any apply here?
 
i need some major help i know the formula for a= vf-vi/t
 
Try considering vertical and horizontal components separately, and look at the equations I gave you in your other thread. Have a go and I'll guide you, but I'm not going to set up every one of your questions for you.
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
