I did this but the problem never gave a mass. The angle is my desired result. Gravity is acting on the y direction F=mg. So I found acceleration in the x direction so...can I find the angle with the acceleration known even if the mass is not given?

Question: A crate of oranges slides down an inclined plane without friction. If it is released from rest and reaches a speed of 5.832 m/s after sliding a distance of 2.29m, what is the angle of inclination of the plane with respect to the horizontal? I first set up a free body diagram...

Consider two cars one a chevy, one a Ford. The Chevy is speeding along at 50m/s (mph) and the Ford is going half the speed at 30m/s. If the two cars brake to a stop with the same constant acceleration, are either the amount of time required to come to a stop, or the distance traveled prior to...

Homework Statement My question is how do you use the symmetric equation. For instance I have a question that states: A line L has parametric equations x=4+3t, y=3+4t, z=9-4t. Determine whether or not the points given lie on the line L. points (17, 14, -9). Homework Equations I know that...

Homework Statement A line L passes through the point P(5,1,6) and is parallel to the line M with given parametric equations x=4+4t, y=8+5t, z= 9t. Find the parametric equation of the line L. Homework Equations Well the things that I do know is that the vector to this problem is <4...

Homework Statement Let vector 'v'=<1,-1,5> and vector 'w'=<40,-19,-1>. Represent 'w' in the form of 'w'='g'+'h', where 'g' is parallel to 'v', and 'h' is orthogonal to 'v'. This is related to the dot product. But I don't know where to begin Homework Equations 'v' is a vector. 'g'...

I put s=2 because I was finding a multiple of the two vectors given. Then I calculate 3s=6, that would then calculate to c=2.

Homework Statement Given vectors b and c are they parallel? If so find such scalar s that c=sb, otherwise write N for no. a) b=<0,3,4>, c=<0,6,-8) b) b=<10,6>, c=<-15,-9> Homework Equations c=sb is a property of the dot product. The Attempt at a Solution For a) I put No...
