A compact car, mass 775 kg, is moving at 1.00 multiplied by 10^2 km/h toward the east.

(a) Find the magnitude and direction of its momentum.

(b) A second car, mass 2125 kg, has the same momentum. What is its velocity? (in km/h)

2. Relevant equations

3. The attempt at a solution

(a) 775 x 100 = 77,500 N s, to the east.. How do i convert this to kg m/s?

(b) 77,500 = mass x velocity

77,500 = 2125 x V

velocity = 77,500 / 2125

= 164,687,500 or 1.65 x 10^8 km/h
