I am asked this question "Compute the Power when both mass and velocity are changing in time. (First rewrite KE(t) showing the time dependence, then compute d(KE)/dt."
I can get this to the point where there are similarities between my equation and the power equation. What I have right now is (v^2)/2 + vma I am not sure what I did wrong but I think that it is in the first few steps.
What do I need to do to fix this problem?
2.2.1) If in the above collision the masses of the particles are m1 = m and m2= 4m and u1/u2 = 3. Show that the opening anglebetween the paths of the m1 and m2 is 120⁰
2.2.2) If the mass m1 has incident kinetic energy E find the energies of the emerging particles m1 and m2 in terms of E.
Momo with mass m is sliding down an inclined plane that makes an angle o relative to the horizontal. The coefficient of kinetic friction between Momo and the inclined plane is Pk. Obtain an expression
for Momo's acceleration along the incline.
Assign a rotated Cartesian plane so that the acceleration is along the positive x-axis and the normal force is along the positive y-axis.
The component of the weight parallel to Momo's acceleration is Wx = mg
The magnitude of the frictional force is f = Pk
The normal force on Momo is n- mg
With these expressions and applying Newton's second law, we arrive
an expression for Momo's acceleration:
a =
- Pk

- Once again we have two sliders, masses m and m, on a horizontal air-track, so negligible horizontal forces, and vertical forces add to zero. The right hand mass is travelling to the right at speed v, being followed by the other at speed 3v. A spring between them guarantees an elastic collision. After the collision, what are the velocities of the two sliders? Hint: what is the frame of reference that makes this into an easy problem? Speed of left hand mass after the collision Speed of right hand mass after the collision, Please enter your answer in terms of the initial speeds of the two sliders and please enter very simple expressions for the two speeds separated by a comma.
