We know from experience that the Doppler shift of sound from a moving car is easily detectable. Assuming light with a frequency of 8×1014 Hz, calculate the Doppler shift (the difference of the observed and emitted frequencies) for light from a car moving toward you at a speed of 210 m/s.

An open railroad car of mass 2404 kg is coasting with an initial speed of 18 m/s on a frictionless, horizontal track. How much water (in kilograms) has accumulated in the car
It bounces off with the same speed and angle. If the ball is in contact with the wall for 0.175 s, elucidate what is the average force exerted on the ball by the wall?
