Dos carros de igual masa, 1 300 kg, chocan en una colisión completamente inelástica, cuando uno está haciendo alto en un semáforo en rojo y el otro lo impacta por detrás a 50 km/h. ¿Cuál es la velocidad inmediatamente después de del choque a la que avanzan juntos?

step-by-step explanation:

hunhgunyt7 in u uuuhiuteu

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
