Okay, so I think I am getting normal force now from that example. So if I apply what is in this problem for my inclined problem, this should be the same I believe.

A 30000kg truck traveling at 31.3 m/s goes up a 100m frictionless inclined plane. What angle must the inclined plane be above...
I am not too sure whether I am doing this correctly.
The problem is basically a mini-cannon aimed at a 60 degree angle, hits a target on the ground 0.8m away. I am suppose to find the initial velocity.
This is what I did:
Cut the distance in half, assuming the mini cannon-ball will reach...
I'm suppose to find the ordered pair (x,z) for components of the vector R(AB), which I am suppose to be able to find by R(AB) = R(B) - R(A).

So far, I solved for the components of the vector of B, and the vector of A.
Vector...
19.6 m/s + (-9.8 m/s^2)(1 s)
That makes it 9.8 m/s right? It will continue the same trend as well...
0: 19.6 m/s
1: 9.8 m/s
2: 0 m/s
3: -9.8 m/s
4: -19.6 m/s
5: -29.4 m/s
6: -39.2 m/s
Is that right?
There's actually no possible way to plot all 6 velocities I'm guessing.
I have a predefined graph, and it only goes to -25, and +25 on the y-axis (which is in meters). I initially was doing speed, but it doesn't fit (it's suppose to fit).
The following hints were given:
"The acceleration of the stone (due to gravity) is constant. Therefore, the slope of the...
Well, this is really confusing me. I am suppose to be graphing a given situation into a v(t) vertical velocity graph.
The following occurs in 6 seconds (6 points on the graph):
Starting at y = 0 m, a stone is thrown straight up on the edge of a cliff until it reaches its maximum height at 2...
Has anybody ever bought an international edition of a physics textbook? Are they significantly different from the U.S. version? (Same problems except with only SI units?)
Well here is the beginning of it:
[-6(-4)^(n-1)] - 9 + [8(-4)^(n-2)] + 12
This is suppose to simplify to 2(-4)^2 + 3.
But I have no idea how that 2(-4)^2 was obtained. Could anybody explain how that would work?
