The driver of a white ford bronco (m = 1700 kg), traveling west on 224 isn’t paying attention and crashes into a kia sol (m = 950 kg) traveling south on friendsville, on level ground at the intersection. on impact, both drivers lock their brakes. the bronco and kia stick together and slide to a stop over a distance of 18.2 m at 50 degrees south of west. the coefficient of friction between the tires and the road is 0.72. what momentum do the two locked together cars have after the crash?

Suppose that a mass of 2 kg is attached a spring whose spring constant is 50. the system is damped such that b = 12 . the mass is set in motion with an initial velocity of -8 m/s at a position 0 meters from equilibrium. set up and solve a differential equation that models this motion. write your solution in the form a cos ( ω t − α ) where α is a positive number. use your solution to fill in the information below: what is the amplitude of the motion? what is the value of ω ? what is the phase shift?

Carbon tetrachloride (ccl4) is ionic or convalent
