variable acceleeration

[paper cedar]

need help

second part dont get it

[lapis widget]

It means to find the velocity at time t3

Cause that's the last time x was =0

V=dx/dt

Sub t3 into the equation v

[paper cedar]

what about this

@lapis widget

Thank you by the way

Nws

you got the equation for the acceleration so if you integrate it you get the velocity and if you integrate the velocity you get the displacement

Now the thing is to get the value of the +c for each

That last sentence gives you two pieces of info

That at t=1 the velocity is 0

Cause it says instantaneous rest

And also at t=1 the displacement is 9

So sub with t=1 into the equation for velocity first and get the c

Then integrate and do the same for displacement

ahhh right, thanks man!

@lapis widget im so sorry for the late reply
