Homework Statement
The first part is to find a quadratic parametric curve f(t) = (p1(t),p2(t)) which passes through the points (0,0) (1,1) and (2,1). (hint: find two interpolating polynomials, one for x and one for y)
Second part is to find the control points for the curve( ie. change...
Homework Statement
If the pressure inside a tank of heavy water is raised by 1 atmosphere, what happens to the tank?
Homework Equations
The Attempt at a Solution
Not sure where to start.
There is a "cannon" pointing downwards with a spring inside where an object is inside and compressed up 1 meter.
mass of object = 50.0kg
k = 49050
height = 0 at bottom of cannon.
Potential energy at start = mgh + 1/2kx^2
Kinetic energy at end = 1/2mv^2
I had to first solve for the object...
Homework Statement
Derive an equation for velocity based on time with drag.
Homework Equations
The equation is: v(t) = F/b (1 - e^(-bt/m))
The Attempt at a Solution
There's some math on paper, but I got down to:
F - bv = ma
a = dv / dt
F - bv = m*dv/dt
dt = m*dv / (F -...
Homework Statement
A 160kg box is on a plane with an incline of 35 degrees. A rope is attached to the box and a pulley at the top of the ramp and has a tension of 1240 N. The static coefficient of friction is 0.45. Will the box move up the ramp? If so, what is its acceleration?

Homework Statement
A block of mass M is on a plane with an incline of Theta. What horizontal force must the ramp be pushed so that the block does not move relative to the ramp.
This is to be solved generally.
Homework Equations
Force of gravity on block: m*g*sin(theta)
Normal force...
