A space station travels 5000 kilometers in 4 hours. What is its speed? Group of answer choices

20000 kilometers/hour

12500 kilometers/hour

2000 kilometers/hour

1250 kilometers/hour

it is 1250 because it moves 5000 in four hours then it means that it is moving  at 1250 an hour

Explanation:

no. dot product   =0 when vecs at right angles

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
