hey mate
average acceleration = change in velocity /time
so fr ur question it will be
5i+5j+5k/5
so u will get i+j+k
which is in vector
so its magnitude will be root3
i hope u understood!!!

hey mate firstly find average velocity by simply change in velocity
mean v2- v1
5i -j -3k
-10i- 4j-2k
_________
-5i-5j -5k
by taking magnitude we have .
√ (5)²+(5)²+(5)²
√75
devide it by time to get average acceleration..
√75 ÷ 5
answer is √3
hope it may help you ☺
