    Regarding another momentum problem

    a 4kg object traveling west a 25 m/s hots a 15 kg object at rest. the 4 kg object bounces eastward at 8 m/s. what is the speed and direction of the 15 kg object. i set it up at (m1)(v1)+(m2)(v2)= (mtotal)(vfinal) 100/ 19 = x 5.26 = x except i solvedfor the final v IM STUMPED...

    Understanding Momentum: Solving Problems with the FT=MV Formula

    i have 3 problems for homework and I am stomped. i don't know if the way I am solving the problem is right. I am using the FT=MV formula for all 3 problems. 1) a football player of mass 120 kg is traveling at 20 m/s collides with another player and comes to rest in 1.5 s. what is the force...
