Which of the following BEST describes what occurs in a fusion reaction?

A. Two low mass nuclei are joined to form one nucleus and gives off energy.

B. Electrons are shared between the nuclei.

C. A chemical reaction occurs between the nuclei.

D. A single nucleus divides into two or more nuclei and gives off energy.

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

god i hope this !
