How to Approach Projectile Motion on an Inclined Surface?

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.

Hi there, I am happy to assist you with these dynamics problems. For problem 11.9, it would be helpful if you could provide more information on the specific problem or concept you are struggling with. Without that, I am unable to provide a specific solution. However, in general, it may be helpful to review the equations of motion and how to use them to solve problems involving acceleration, velocity, and displacement.

For problem 11.15, you are correct in thinking that you need to consider the acceleration and velocity of each component separately. To account for the incline, you will need to break the initial velocity into its horizontal and vertical components, and then consider how the incline will affect the horizontal component. You can use the trigonometric functions of the angle of the incline to help you with this.

I would also suggest reviewing the concept of relative motion and how it applies to projectiles on an incline. This may help you set up the problem differently and solve it more easily.

I hope this helps and good luck with your problems! Let me know if you need further clarification or assistance.
