AI Thread Summary
To solve the projectile motion problem of a third baseman throwing a ball, it's essential to analyze the horizontal and vertical components separately. The ball is thrown horizontally at a speed of 38.0 m/s from a height of 1.20 m, and the distance to first base is 39.0 m. The time it takes for the ball to hit the ground can be calculated using the vertical motion equations, while the horizontal distance can be determined using the horizontal speed. Additionally, to find the angle for a throw that reaches the first baseman at the same height, projectile motion equations must be applied. Understanding these components is crucial for solving the problem effectively.

A third baseman makes a throw to first base 39.0 m away. If the ball leaves his hand traveling horizontally with a speed of 38.0 m/s at a height of 1.20 m from the ground, how far will it go before striking the ground? At what angle must he throw the ball so that it reaches the first baseman’s glove at a height of 1.20 m above the ground.?

What have you done with it so far?
 
Maybe give him a formula... I would but I don't know it.

Whenever you encounter a projectiles problem, remember to treat the vertical and horizontal components of the motion of a projectile separately. Tide is right: tell us what you've done and we'll go from there.
 

Thread 'Rolling without slipping on a curved surface'

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 .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

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...
