Can anybody offer any assistance with the following problem please?
A projectile is shot, in windy conditions, with initial speed v at an angle of 60 degrees from the ground. Because of the wind, which blows horizontally, the projectile is subject to a viscosity force, in the direction of the wind, of the form Fv = -c.vx (where vx is the component of the velocity of the projectile in the horizontal direction and c is a constant).
[nb. In Fv = -c.vx, the first v and x are subscript. Hope the question is clear. I don't how to type subscript characters.]
Determine the position of the projectile, x(t) and y(t), for t ≥ 0 and compute the distance at which the projectile lands.
I'd be very grateful for any help with this.
