A water jet starts at a point X and reaches its maximum height at a point Y. Air resistance has a negligible effect on the motion of the water jet. (i) State the direction of the force acting on the jet at Y. (1 mark)

(i) The only force acting on the water jet is gravity which always acts vertically downwards so the force at Y, as well as every point between X and Y, is down.Simply writing "down" would still get...

Solve the equation 3^(5x-2)=4^(6-x), and show that the solution can be written in the form log10(a)/log10(b).

So we have the equation initially in the form 3^(5x-2)=4^(6-x), and as the solution involves log10, then a sensible first move would be to take log10 of both sides, giving log10(3^(5x-2)) = log10(4^(6-x)). U...

Prove that (sinx + cosx)^2 = 1 + 2sinxcosx

Starting on the left hand side we can expand out the brackets to get: (sinx + cosx)(sinx + cosx) sin 2 x+sinxcosx+sinxcosx+cos 2 x Grouping together the like terms we can rearrange it to be: sin 2 x + cos 2 ...
