A block of mass m 2.0 kg is dropped from height h=40 cm onto a spring of spring constant k = 196

A block of mass m = 2.0 kg is dropped from height h = 40 cm onto a spring of spring constant k = 1960 N/m. Find the maximum distance the spring is compressed.

i love you so much bro you have a solution to every Q in our previous exams you don't know how much you've helped me

[SmokingBlackBear]

why is h(height) above the spring at the start, the question states dropped from a height of 40cm would that not mean 40cm from the ground?

Thanks for this. My professor assigned a problem like this but didn't bother to properly teach us how to do it. My answer isn't exactly what's in the back of the book, but it's within a hundredth of a decimal place, so I'll take it!

Excellent love from India 🌅. Thanks for supporting us.

may i ask, if there is no h, and the block is just released at the top end of the spring, why cant we just use F=kx? Because I see a question like this, and what I get is half of the exact answer if I use F=kx

[vanessaantuna]

So i tried solving this with plugging in the numbers first but i didn't get the same answers and i cant find out why

why do you not have more subscribers thank you so much

[ahmadfodeh]

when does the block reaches its maximum kinetic energy ?

[anikchakraborty]

Why the height is taken from the top and not from ground??

[abzshaker]

why is there no kinetic energy since it is falling

[JeremyStefun]

I have solved these types of problems by ignoring the x in the gravitation potential energy equation i.e [U = mgh instead of U = mg(h+x)] and then just added 0.01 meters to my final answer and it was always correct. mgh = (1/2)kx^2 = answer + 0.01 .... i was wondering why this is.
