A nuclear power plant is built alongside a river. What measurements should a monitoring station downstream record to be sure that the proper procedures are being followed at the power plant? density and radiation levels
radiation levels and dust levels
salt concentration and temperature
temperature and radiation levels

it would be c. predictability

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
