Need help in MatLab, I haven't used this program in a while... 1. 7u+3v+2w-x+7y-2z=1 3u+9c+1w-2x-9y+5z=7 5u+7v+3w-2x+7y+z=-5 2u+1v+9w-2x-7y-6z=14 9u+1v-8w+2x-7y+3z=22 u+2v+3w+4x+5y+6z=69 Solve for u,c,w,x,y,z using MatLab I know it is solving linear equations using matrices but how can I do...

It is v< (less than) vf. What I have thus far is a=g(Vf^2-V2^2/Vf^2) a=g(1-(V2^2/Vf^2) Integral 0 to V (1/1-(V^2/Vf^2) dv=Integral 0 to T gdt 1/2 ln V+Vf/V-Vs=gt t=1/gy ln V+Vt/V-Vt dv/dt=g(1-V^2/Vf^2) 1/2a ln v+a/v-a 1/2 ln V/Vf+1 / V/ Vx-1 Integral 0 to V gt

1. When a particle falls though the air, its initial acceleration a=g diminishes until it is zero, and thereafter it falls at a constant or terminal velocity vf. If the variation of the acceleration can be expressed as a=(g/v^2f)(v^2f-V62), determine the time needed for the velocity to become...

if you got 15, for the answer that's not it also

can you post how you did it please

need help i don't know what to do

can someone please help me

help me solve this please

Integral 4s^2=4s^3/3

1. A particle is moving along a straight line such that its acceleration is defined as a=(4s^2)m/s^2, where s is in meters. If v=-100m/s when s=10m and t=0, determine the particles velocity as a function of position. 2. V=ds/dt a=dv/dt 3. V=ds/dt a=dv/dt 1/dt=ads*vdv Integral 100 to s...

Can anyone help me?

dv/dt = (g/v^2f)(v^2f-v^2)? like that? how? can you please show me

make the forces and gravitation = to each other? can you help me please?

find the time for the velocity to become v<vf. (V less than Vf)

alright, i'll do that
