A2444 kg car moving at 24.9 m/s east collides with a 3329 kg truck moving at 15.7 m/s west. after the collision the two vehicles stick together, what is their combined velocity

1.49 m/s East

Explanation:

From the law of conservation of momentum, the sum of initial momentum equals the sum of final momentum

Momentum, p=mv where m is the mass and v is the velocity

where is the common velocity, and are velocities of car moving East and West respectively, and are masses of car moving East and West respectively

Taking East direction as positive then west as negative then substituting 2444 Kg for   and 3329 Kg for , also 24.9 m/s for and -15.7 m/s for

chemical properties of thing

i sometimes feel that way too. i feel that i should hurt someone because they hurt me, but i wouldnt do it. that would make things so much worse i have so much experience with this stuff
