A600kg car is moving at 5 m/s to the right and elastically collided with a stationary 900 kg car. what is the velocity of the 900 kg car after the collision if the 600 kg car moves left at .714 m/s?

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k

Wavelength,frequency,and energy are related.what happens to a wave as it’s wavelength gets shorter?

In order of decreasing light-transmitting capabilities of materials, which is the correct sequence? a. transparent -> translucent -> opaque b. opaque -> transparent -> translucent c. opaque -> translucent -> transparent d. translucent -> transparent -> opaque
