A bag of salt was projected vertically upwards from a height of 1 and remains in the air for 6.1 s.
(a) What speed was the bag thrown at, and
(b) What was the distance the bag travelled before returning to the height of 1 m?
The equation x3-bx2+cx-d = 0, where d>0, has roots α, ß and αß. Show that (c+d)2 = (b+1)2d.
New to forums and not sure if this is how things are done. Sorry in advance!
And thanks!
