99 ball b, with a mass of 30kg, is moving to the left at -10 m/s. with what velocity should ball a, with a mass of 10 kg, move to the right and collide with b, so that ball a rebounds with a velocity of -30 m/s, and ball b with velocity of 10 m/s, after the collision? assume the collision to be perfectly elastic. use the formula for perfect elasticity. m1v1(initial) + m2v2(initial) = m1v1(final) + m2v2(final) m1 = mass of object 1, m2 = mass of object 2 v1 = velocity of object 1, v2 = velocity of object 2

With what velocity should Ball A, with a mass of 10 kg, move to the right and collide with B, so that Ball A rebounds with a velocity of -30 m/s, and Ball B with velocity of 10 m/s, after the collision? Assume the collision to be perfectly elastic.

Use the formula for perfect elasticity. m1v1(initial) + m2v2(initial) = m1v1(final) + m2v2(final) m1 = mass of object 1, m2 = mass of object 2 v1 = velocity of object 1, v2 = velocity of object 2

-30 in velocity

1/6

step-by-step explanation:

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
