Baseball - (2D?) Kinematics - Projectile Motion

AI Thread Summary
A baseball is hit at 45 m/sec at a 50° angle, and the right fielder, 300 m away, needs to determine the speed required to catch the ball at 1 m height. The problem involves 2D kinematics, requiring the resolution of the initial velocity into x and y components. The fielder calculated he needs to run at 13.56 m/sec to catch the ball, which is deemed impossible. The discussion highlights confusion over the appropriate equations and the need for graphical representation to solve the problem. Ultimately, the fielder's speed requirement exceeds realistic limits, raising questions about the feasibility of the catch.

Homework Statement



A batter hits a baseball at a speed of 45 m/sec at an angle of 50° above the horizontal. The right fielder, who is standing 300 m away from the batter, begins to run when he sees the bat hit the ball. If the fielder runs at a constant speed, what speed does he need to run in order to catch the ball at a height of 1 m above the ground? Can he make it?

P.S. The batter hits a grounder.

Homework Equations



Not sure. I think this one is used.

Vfx = Vox + atx

Please help if you can. I've honestly worked on this problem for at least two hours, but I don't understand it.

I believe you have to use Xf=Xi+vt+0.5at^2 to solve
 
I asked someone else, and he said that I should draw an accurate graph of this problem. But, I wasn't taught how to do this in class. I think my professor just used trigonometry or the equation you suggested, semc. I'm confused...
 
I am not sure what your friend suggested about drawing a graph but i believe drawing the projectile might help. Firstly you have to know that this is a 2D question so the equation has a x and y component. Just resolve the initial velocity into the x and y component and use the equation and you should be able to get the answer.
 
Thanks, semc. My homework assignment is due in a few minutes, so I can't type all that I wrote, but I calculated that the fielder must run 13.56 m/sec to catch the ball, which isn't possible.
 
Does Usain Bolt play baseball? =D
 
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...
