backboardForce of thewind, Fw0.35 m2.00 mWeight of postarrangement15°0.25 mWeight of baseA portable basketball set has a base and a post arrangement. The post arrangementconsists of a post, backboard, hoop and net. The base can be filled with water toincrease stability. The maximum weight of the base is about 810 N and the weightof the post arrangement is 26.0 N. The basketball set may topple over when thewind blows due to the large area of the backboard.a) Determine the minimum force of the wind, F, that will cause the basketball setto be blown over when it is at the angle shown. Ignore the effect of the wind onthe base.b) The base is filled with sand instead of water. The density of the sand is greaterthan the density of the water. Justify what would happen to the value of Fwcalculated in part (a).2.

Answer: Minimum force of the wind required, Fw = 80.24 N The required force of the wind will get…
