(b) if the collision is perfectly elastic‚ their individual speeds if the pucks do not stick together. 2. A bullet of mass 10 g has a muzzle velocity of 300 m/s. Find (a) the momentum of the bullet (b) the recoil velocity of the gun if its mass is 2.0 kg. 3. A 70 kg man dives away

as the velocity. P = m * v (kg. m/s) During a collision‚ it is usually straightforward to measure the mass and velocity of an object‚ so that its momentum just after the collision and just before the collision can be found. The collisions include elastic collision (one in which the total kinetic energy of the system after the collision is equal to the total kinetic energy before the collision‚ ideally with no loss of energy due to sound‚ heat‚ light‚ or deformation) and inelastic collision (one in

Solution The elastic modulus versus volume percent of WC is shown below‚ on which is included both upper and lower bound curves; these curves were generated using Equations 15.1 and 15.2‚ respectively‚ as well as the moduli of elasticity for cobalt and WC given in the

ELASTIC DEFORMATION AND POISSON’S RATIO E 45 – Materials‚ Friday 8:00 am September 21‚ 2012 Due: October 19‚ 2012 Abstract A tensile test was performed on a 4140 steel sample and the axial and transverse strains were measured. Data points were collected at incremental loads and graphed to determine the elastic modulus (30.4 x 106). Poisson’s ratio was also calculated from the dataset and determined to be 0.29. These experimental values agree closely (within

The pendulum shows elastic collision and conserved momentum. In this set up‚ no momentum is actually lost. Ball 0 just transfers its momentum to stationary ball 1 which it collides with(head-on collision) so ball 0 is put to stop then ball 1 collides with ball 2 causing ball 1 to stop and transfer its momentum to ball 2 and so on until the momentum gets transferred to ball 4 then ball 3 collides with ball 2 and the cycle continues.

to achieve: I believe that the purpose of doing this is to allow me to demonstrate my understanding of Elastic potential energy. And the projectile concepts of the effect of changing potential into kinetic energy and for me to demonstrate my ability to apply elastic potential energy to a scientific investigation. What am I going to do and what will it prove: I am going to use an elastic band and release it from different tensions I will then measure how far it ‘flies’. Doing this
