A tiny wintock which has tcm x cm x 4cm dimensions and a density of 06 gem is slowly released into a container files with water with = 1000 kg/m3, the cost of the weten te start changes to p = 27 g/cm determine the acceleration of the block as it is sunk to the bottom of the container

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray

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
