In the figure here, a red car and a green car move toward each other in adjacent lanes and parallel to an x axis. At time t = 0, the red car is at x_r = 0 and the green car is at x_g = 222 m. If the red car has a constant velocity of 25.0 km/h, the cars pass each other at x = 43.0 m. On the other hand, if the red car has a constant velocity of 50.0 km/h, they pass each other at x = 76.3 m. What are (a) the initial velocity and (b) the (constant) acceleration of the green car? Include the signs.

Mechanic Physics: In the figure here, a red car and a green car move toward each other in adjacent lanes and parallel to an x axis. At time t = 0, the red car is at xr = 0 and the green car is at xg = 217 m. If the red car has a constant velocity of 23.0 km/h, the cars pass each other at x = 43.6 m. On the other hand, if the red car has a...

A sound source A and a reflecting surface B move directly toward each other. Relative to the air, the speed of source A is 29.7 m/s, the speed of surface B is 63.5 m/s, and the speed of sound is 330 m/s. The source emits waves at frequency 1350 Hz as measured in the source frame. In the reflector frame, what are (a) the frequency and (b) the wavelength of the arriving sound waves? In the source frame, what are...

A completely inelastic collision occurs between two balls of putty that move directly toward each other along a vertical axis. Just before the collision, one ball of mass m1 is moving upward at speed v1 and the other ball of mass m2 is moving downward at speed v2. In the following, if there is gravity it has acceleration g. (a) Suppose the collision happens very fast. What is the velocity of the putty immediately after the collision? (b) Suppose the...
