You are working as a forensic physicist, analyzing a collision for the state police. According to witnesses, a car heading east and a truck heading south collided in an intersection. Photographs taken at the scene show that the car was severely damaged. Which of the following apply to this situation?

(A) |p|car, initial+|p|truck, initial=|p|car, final+|p|truck, final
(B) pcar, x, initial+pcar, x, final=ptruck, x, initial+ptruck, x, final
(C) pcar, y, initial+ptruck, y, initial=pcar, y, final+ptruck, y, final
(D) Ecar, initial+Etruck, initial=Ecar, final+Etruck, final
(E) pcar, x, initial+ptruck, x, initial=pcar, x, final+ptruck, x, final

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

it is a negative acceleration

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 !
