Projectile Motion (Vector Quantities)

AI Thread Summary
The discussion revolves around determining the truth of various statements related to vector quantities and projectile motion. The participant provides answers to six statements, affirming that single vectors can be represented as pairs of components, that vector quantities are not described by magnitude alone, and that velocity is indeed a vector quantity. There is consensus among participants that the answers are correct, with a note that some scalar quantities may also require direction for complete information in specific contexts. Overall, the discussion confirms the understanding of vector and scalar properties in physics.

Homework Statement


Determine whether each statement below is True or False.
1. T/F Single vectors may be represented as pairs of vector components.
2. T/F Vector quantities are completely described by magnitude only.
3. T/F A scalar quantity requires both magnitude and direction for a complete description.
4. T/F Vector quantities are graphically represented using arrows.
5. T/F As the angle between the ground and a vector increases, the vertical component of the vector increases.

ya.Everything's right.
but some scalars require direction also for complete information.For eg:current produces magnetic field but it's direction can only be determined if u know the direction of current.
 
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 .
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...
Thread 'A bead-mass oscillatory system problem'
I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
