A boat of mass 800kg is pulled along the sand at constant velocity by a cable attached to a winch.the cable is at an angle of 15° to the horizontal.
IF the tension in the cable is 4kN show that:
The normal reaction of the sand on the boat is about 7kN

Looking at the vertical forces only, the up forces are R and the vertical component of 4000KN and the down force of 800 x 9.8. The forces equate to zero so you can work out R.
