Two cars of the same mass collide at an intersection. just before the collision one car is traveling east at 50.0 km/h and the other car is traveling south at 60.0 km/h. if the collision is completely inelastic, so the two cars move as one object after the collision, what is the speed of the cars immediately after the collision? km/h

v=39.051 m/s

Explanation:

Given

Two cars having same mass, let say m

One is traveling east 50 km/h and one is traveling 60 km/h south

after collision they stick together and move with common velocity v at angle of

conserving Momentum in east i.e horizontal direction

---1

conserving momentum in south direction i.e. in vertical direction

---2

Divide 1 &2  we get

w.r.t east clockwise

Put value of is equation 1

the body's situation won't change the forces are equal opposit and on the same body

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19
