Answer:
Some details are missing in the question, here are the details ; A proton initially has v = -6.5i + 17j + 13k and then 8.00s later has v = -2.8i + 17j - 9.3k (in meters per seconds).
a) proton's average acceleration in unit vector notation = 0.46i - 2.78k
b) Magnitude = 2.85m/s2
c) angle between and the positive direction of the x axis = 279.39 degree (counter clockwise)
Step-by-step explanation:
The detailed and step by step explanation is as shown in the attachment
6. d
7. a
8. f
9. b
10. c
11. (7x3)+(7x2)=
21+14=35
7x5=35
12. (6x3)+(6x3)=
18+18=36
6x6=36
13. (2x3)+(6x3)=
6+18=24
8x3=24
14. (9x5)+(9x3)=
45+27=72
9x8=72
Answer:
I disagree, because 26540 is bigger then 50
Sin(45°)= x/3√(2)=P/H
1/√(2)= x/3√(2)
1/√(2)×3√(2)=x
x= 3
Therefore, B is your answer.
Hope this answers your question!!
