Homework Statement
A cricketer strikes the ball at a height of 1 metre. It passes over a fielder 7 metres from the ball at a height of 3 metres, and hits the ground 60 metres from the bat. How fast was the ball hit?
The issue I have here is that after forming a quadratic in terms of tanα, you have u in as an unknown and subbing it back in gives incredibly messy algebra, which makes me think it's not the best way.
Homework Equations
u in x direction= ucosα s in x direction= utcosα
u in y direction= usinα s in y direction= utsinα - 4.9t^2
The Attempt at a Solution
My solution attempt is pages long and contains stupidly complex algebra, I think I am fundamentally missing something as the maths seems too fiddly for a fairly straightforward mechanics course.
Any tips to make the problem easier, or preferably a solution would be great. Thanks
