Calculating Launch Velocity for a Motorbike Jump

AI Thread Summary
To calculate the launch velocity needed for a motorbike to clear a 40m gap while landing 15m below the ramp, one must consider the ramp's angle of 53 degrees. The problem requires applying projectile motion equations, factoring in both horizontal and vertical components of the jump. Drawing a diagram can help visualize the scenario and clarify the known variables and what needs to be calculated. Some participants express confusion over the sufficiency of the provided information for solving the problem. Ultimately, understanding the physics of projectile motion is essential for determining the required launch velocity.

some guy on a moterbike rides up a ramp to clear a gap of 40m, where the flat landing is, situated 15m below the horizontal line of the tip of the ramp. The ramp is at an angle of 53degrees above the horizontal. what velocity must the rider lift off the ramp with?

I serioulsy have no ideas on where to start with this, I've tried several different scribbles and got nowhere. Some help would be appreciated! thanks

Start by drawing a picture and then write down what you know (given from problem) and then write down what you need to know. Hopefully this will get you started in the right direction.
 
I have a picture, and i know the info. but it seems to me like there isn't enough info, i can't work with it.
 

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...
