I have a lab in which a moving marble collides with a still one. What changes could I make to reduce the amount of kinetic energy loss in the collision? The track for the marbles is a piece of card stock paper.
I was thinking:
-Use two tubes as a track which will reduce the amount of...
Uhhh the mass is a marble. And I'm trying to measure the average force of friction acting on the marble during its journey. I'm only in 12 U physics so it wouldn't involve that as I haven't learned it yet. I'm pretty sure this should be dealt with from an energy perspective.
Homework Statement
We have to make a roller coaster for our school project. This coaster starts with a spring. In this coaster, there is a collision. Essentially, I need to find the energy lost at the collision, and the average force of friction. Homework Equations
Em1=Em2
W=Fd
F=ma
A=DELTA v/...

Homework Statement
1.2 kg cart slides down frictionless ramp from a height of 1.8m and then onto a horizontal surface where it has a head-on elastic collision with a stationary 2.0kg cart cushioned by an ideal Hooke's Law spring. Maximum compression of spring is 2.0 cm
Determine the spring...
There's a sketch of the situation given to you in the textbook
Basically there are 2 right angle triangles. One regular triangle. The non-right triangle is 100m long. The angles given for the right angle triangles are 18 and 20. That's all that's given to you.

Suppose Romeo is serenading Juliet while she is on her balcony. Romeo is facing north and sees the balcony at an angle of elevation of 20 degrees. Paris is observing the situation and is facing west. Paris sees the balcony at an angle of elevation of 18 degrees. Romeo and...
Yea your explanation is right. Thanks
Anyway the work states that you cannot solve by factoring.
I kind of understand what you're saying. But if I need c= -2.3508d, that wouldn't be a number which I was given.
Homework Statement
Basically I have to fill out this ax^2+bx+c using the given numbers
-8,-4,-3,1,2,5,6,7,9
The solution must be the one provided
So it works like this (example is just with regular addition)
1 2 3=5
8

=
18
Here is the problem...
