Explanation:
because it doesn't depend upon other unit like kg meter and second
It is 6 g/cm3 because density cannot be negative, and it is not speed in which the unit would be m/s.
Answer: The question has some missing details. The initial velocity given as u = -6.5i + 17j + 13k and the final velocity v = -2.8i + 17j -9.3k.
a) = (1.82i - 9.69k)m/s2
b) magnitude = 9.85m/s2
c) direction = 280.64 degree
Explanation:
The detailed and step is shown in the attachment.
I think that the answer is A
