8. A Ferris wheel with diameter 18 m and rotates with constant speed of 3.8 ms. Calculate the magnitude and direction of the force which the seat exerted on a 40 kg rider at
the
i. lowest point of the wheel. (Ans: 456.4 N)
ii. highest point of the wheel. (Ans: 328.4 N)

pe = weightxheight = 2000x1000=2,000,000joules

true tan speed = ang vel x radius

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
