A glider of weight 2500N is being towed with a constant speed by a four-wheel drive vehicle. The tow-rope is inclined at 25 degrees to the horizontal and the glider is inclined at 30 degrees to the horizontal. The air resistance has magnitude R Newtons (acting at a bearing of 330 degrees) and the lift has magnitude L Newtons acting 30 degrees to the horizontal (opposite directio to tension). Calculate the values R and L, given that the tension is 3000N.
The answers are 470N and 4620N respectively
