Projectile Motion Homework: Calculating Net Height for Daredevil Cannon Launch

AI Thread Summary
A daredevil is launched from a cannon at a 45-degree angle with an initial speed of 25.0 m/s, aiming to reach a net positioned 50 m away. The required height for the net to catch the daredevil is calculated to be 10.8 m above the cannon. The user attempted to apply the projectile motion equation but encountered difficulties in reaching the correct answer. Clarification on the calculations and the correct use of the projectile motion equations is requested. Understanding the physics behind the motion is essential for solving similar problems effectively.

Homework Statement


A daredevil is shot out of a cannon at 45degrees horizontal with an initial speed of 25.0m/s. A net is positioned at a horizontal distance of 50m from the cannon from which it is shot. At what height above the cannon should the net be placed in order to catch the daredevil?


Homework Equations



P=X/ViCos(theta)


The Attempt at a Solution


i tried this equation but it did not work out. The answer is supposed to be 10.8m. Please explain it if you get this correct. Thank you!

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...
