For a stationary object on the earth's surface the centrifugal force is given as o'r. if the object is set in motion eastward by an impulsive force derive an equation for the total centrifugal force acting on the parcel. 4 marks) a) b) from a) derive the components of the coriolis acceleration. c) if a baseball player throws a ball westward a horizontal distance of 100 m at 30 (8 marks) latitude in 4 seconds, by how much is it deflected as a result of the rotation of the earth? (ω= 7.29×10-s rads-')

second mirror gathers light from a faraway object and reflects it to another mirror. - a.

that would be because of both gravity and friction. so     c

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
