A paraglider of mass 90 kg is pulled by a rope attached to a speedboat. With the rope making an angle of 20 degrees, to the horizontal the paragilder is moving in a straight line parellel to the surface of the water with an acceleration of 1.2ms^-2. The tension in the rope is 250N. Calculate the magnitude of the vertical lift force acting on the glider.

    but the answer i 985, with the vertical component of tension?

    I think its 900-85.5=814.5

    vertical force = 900+ (sin 20* 250)
