yea arccosh. So its right in that case?

can I rewrite the arccosh(x) as ln(x+sqrt(x^2-1))?

oops I did another way, I found time taken to travel h metres, called it b, then found the velocity at time b, so v(b) I did integral from o to b of v(t)

could you pls provide an assist? ^_^

for c it asks for impact velocity in terms of h is my answer correct I got v(h)=sqrt(g/k) tanh(arccos(e^(h.sqrt(k/g)))

thankyouuu <3 <3 <3

A parachutist weighing m=75kg jumps from an airplane at an altitude of h meteres with initial vertical velocity v0=0. Let v(t) be his instantaneous vertical velocity at time t with the downwards direction taken as positive. Suppose that he deploys the parachute immediately after jumping from the...

hey folks! switched career paths from med focus to maths focus, started maths this sem after 3 years lol. will post q's, any help appreciated 1. find 8th derivative of exp(-sqrt3t).sint i got 2^7.sqrt3(exp(-sqrt3t)sint) am i right?

BUMP

Hi pls casual

See just from this I realise no point talking to you because you dont even understand what youre saying. Lol. The arrogance is astounding. You want to continue? with what? You are making only silly points and drawing all the wrong conclusions. But feel free to write, if writing is a "release"...
