1.

If bar(u) = 2bar(i) - 2bar(j) + 3bar(k) and the final velocity is bar(v) = 2bar(i) - 4bar(j) + 5bar(k) and It is covered in a time of 10 sec, find the acceleration vector.

Answer»

`(3bar(i) - 2bar(J)+2bar(K))/(10)`
`(-3bar(i) + BAR(j)+2bar(k))/(10)`
`(-3bar(i) - 2bar(j)+2bar(k))/(10)`
`(-bar(j) + bar(k))/(5)`
