Hey there guys I just have a question to ask some of you. Given the occurence of time dilation being related to an objects state of motion I have an interesting thought.
This is a very general question, my teacher only briefly covered this topic in class as it's not part of our course but it...
Homework Statement
In coming to a stop a car leaves skid marks 92m long on the highway. Assuming a decceleration of 7.00 m/s^2 , estimate the SPEED of the car just before braking.
I have a question though, is my approach ok? You can see my confusion in various parts of my procedures below...
Homework Statement
I'd just like someone to see if I answered correctly. I'm having a bit of difficulty grasping the vagueness of the displacement in these questions I've been getting in my textbook. From what I gather the displacement is relative to the vector points, (the two x points in...
I have another question.
My projectile starts at point 0,5
I am given this formula to solve the range of the projectile if y isn't equal to 0
I'm fine with it until the end, it says y0, why y0? Does it just mean insert the value of y that the projectile starts at?
Projectile Motion Question
Homework Statement
A cannon fires a projectile
Velocity = 40 m/s
The angle of the cannon= 35 degrees
solve for Vx= V*cos(angle)
and Vy=V*sin(angle)
I am having a problem understand this concept relative to what the screenshot below shows...
