if i3
i put an extra i in there by accident
i have 2 equations
12-20i-5(i+I)= 0
8-5I-5(i+I)=0
ifi i3 = i+I determine the values by solving 1 and 2 by matrices....
i havent got a clue what to do can anyone do it?
thanks a lot but what is a b and c?
four coplanar forces act at a point in the centre of pic (attached).
i need to determine the value of the resultant force using complex notation (expressing answers in polar and cartesian form, showing results in an argand diagram).
im baffled and dont know what to do, can anybody help me?
please help me do this
a body moving with uniform acceleration exhibits the relationship
s=ut+0.5at^2
s= distance
u= initial velocity
a= acceleration
t= time
if an object falls and passes a point 40m above ground at a velocity of 10m/s how long does it take to hit the ground by:
1. using the quadratic equation
2. graphically
i only need to know one as i will do 2 at college. please help thankyou
