An alpha particle (ma = 6.64 x 10-4 kg) is travelling at 1500 m/s [N] and collides with a proton (mp= 1.67 x 10-27 kg) travelling at 1800 m/s [8]. Determine the final velocities of both particles after this elastic collision.

Automobile fuel efficiency is often measured in miles that the car can be driven per gallon of fuel (mpg). heavier cars tend to have lower fuel efficiencies (lower mpg ratings). which variable (weight or fuel efficiency) is most naturally considered the explanatory (predictor) variable in this context?

If two students are running down the hall toward each other, trying to get to class, and they have the same mass and acceleration, what will happen when they collide? will their forces cancel out or will each one experience a reaction?

Give an example in which the electrical energy changes to light energy
