It must be noted that during an elastic collision both the momentum and kinetic energy are conserved. For the kinetic energy, it can be solved through the equation,
KE = 0.5mv²
Equating the kinetic energies before and after collision,
0.5(60)(8 m/s)² = (0.5)(60)(x²) + (0.5)(0.45)(35 m/s)²
The value of x from the equation is approximately 7.40 m/s
Simplicity of conducting the study is to archival research; as ability to test large numbers participants is to survey.
Yes because colored objects absorb heat and deflect the rest back to the sun unlike the the color white which reflects the rays of the sun completely thus making it appear white
The cyclist displacement is 3 miles south
