In an experiment, the distance an object moved (with constant speed) was 2.34 +/- 0.05 m in the time 0.568 +/- 0.003 s. what were the speed and the uncertainty in the speed?

explanation:

the atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons.

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.

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
