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-')

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
