Molecules act as tiny springs and have vibration energy and frequency. The frequency of CO molecule is 6.42 x 1013Hz. Calculate the spring constant using the effective mass ? = (m1m2)/(m1 + m2).
At time t1 = 2.00 s, the acceleration of a particle in counterclockwise circular motion is (1.00 m/s2) i + (6.00 m/s2) j. It moves at constant speed. At time t2 = 4.00 s (3/4 of a revolution later), its acceleration is (6.00 m/s2) i + (-1.00 m/s2)..
A certain particle has the life time of 10^-7 s, while measured at rest. How far does it go before decaying if its speed is 0.99 c when it is created.
