In my physics class we are constantly taking measurements and calculating uncertainty. Unfortunately my teacher has neglected to teach us how to calculate it and I am at a loss.
Currently I am working on calculating moment of inertia including its uncertainties.
Can anyone walk me through...
Homework Statement
An alpha particle (a helium nucleus, containing 2 protons and 2 neutrons) starts out with kinetic energy of 10 MeV (10*10^6 eV), and heads in the +x direction straight toward a gold nucleus (containing 79 protons and 118 neutrons). The particles are initially far apart, and...
Homework Statement
A car of mass 2200 kg collides with a truck of mass 4500 kg, and just after the collision the car and truck slide along, stuck together, with no rotation. The car's velocity just before the collision was < 35, 0, 0 > m/s, and the truck's velocity just before the collision...
Homework Statement
A horizontal spring-mass system has low friction, spring stiffness 165 N/m, and mass 0.2 kg. The system is released with an initial compression of the spring of 7 cm and an initial speed of the mass of 3 m/s.
(a) What is the maximum stretch during the motion?
(b) What is the...
