How to Approach Projectile Motion on an Inclined Surface?

AI Thread Summary
To solve projectile motion problems on an inclined surface, first analyze the projectile's trajectory as if the incline were not present. Calculate the projectile's motion using standard equations for vertical and horizontal components, focusing on acceleration and velocity. Once the trajectory is established, determine the point of intersection between the projectile's path (a parabola) and the incline (a straight line). This approach simplifies the problem by treating the incline as a boundary that only matters at the point of impact. Understanding these concepts will help clarify the dynamics involved in projectile motion on inclined surfaces.

urgent help with 2 dynamics problems

Hey guys, here are some problems i need help with bad. For 11.9 I got no idea what i am doing here. Here is 11.9:
11.9

Here is 11.15. Here i know how to do a problem with basically a projectile shooting at an angle from the ground but not of one from an incline surface. How would i set this up different? I believe i got to do the acceleration and velocity of each components and then find t, and then i can find d, but that incline is throwing me off. ANy help is appreciated, thanks!

Remember that the projectile doesn't care that the incline is there until it actually hits it. That means that you can find the trajectory of the particle in just the same was as you would if the incline wasn't there. Then to find where it hits you just need to find the point of intersection of a straight line and a parabola.

When you've posted some of your own thoughts on the other problem, then I will too. But not before. :wink:

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Egg Drop Challenge! Need ideas for winning designs'

I was thinking using 2 purple mattress samples, and taping them together, I do want other ideas though, the main guidelines are; Must have a volume LESS than 1600 cubic centimeters, and CAN'T exceed 25 cm in ANY direction. Must be LESS than 1 kg. NO parachutes. NO glue or Tape can touch the egg. MUST be able to take egg out in less than 1 minute. Grade A large eggs will be used.
