A man can swim at 2ms^{-1}( with neglible acceleration) across a current of 1ms^{-1}. He swims towards a point directly opposite his starting position on the river, 10m wide, and always aims to swim across to this point wherever he is on the river

a) find how long it takes for him to swim across

b) sketch the curve the man would swim across the river.

c) find the equation of the curve he swims, assuming the start point is the origin

2. Relevant equations

Any calculus equations

Any SUVAT or motion equations

3. The attempt at a solution

I dont really know where to start at all with this question because its for extra credit but any help, guidance or worked through answers would be great =)
