Sometimes changes in observable properties can indicate a physical change rather than a chemical change. Take, for example, the dissolved sugar demonstration from the previous activity. After the sugar dissolves in the water, it is left out overnight in the petri dish. The next day, all the water has evaporated, but the sugar is left in the petri dish. Was this a physical or chemical change?

it takes about 30 days for it to break down

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
