thanks i was adding both masses for the final momentum, that was my foolish mistake.

An object, with mass 16 kg and speed 19 m/s relative to an observer, explodes into two pieces, one 4 times as massive as the other; the explosion takes place in deep space. The less massive piece stops relative to the observer. How much kinetic energy is added to the system during the explosion...

yes, i was making very foolish mistakes figured it out eventually. But now I am having problems with this question: Tarzan, who weighs 629 N, swings from a cliff at the end of a convenient vine that is 21 m long. From the top of the cliff to the bottom of the swing, he descends by 4.9 m. The...

i don't know what the answer should be i have to input answers online, and so far they have been incorrect

735x^2 - 35.28x - 25.7544 = 0 not working I am getting a very large incorrect number

ok I am trying to solve the quadratic right now, think i made a mistake though i got a really large number

no i did not include .73m in addition to x, I am a bit confused by this can someone explain it a little more to me?

i converted it into meters, and it doesn't work out still. i don't know what's wrong. actually someone else posted this same question earlier and tried the same method and also got it wrong

A block of mass m = 3.6 kg is dropped from height h = 73 cm onto a spring of spring constant k = 1470 N/m . Find the maximum distance the spring is compressed. I tried calculating the gravitational potential energy (mgy) then setting it equal to 1/2kx^2. but its not working out, can anyone...
