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
Answer:
m=5
Step-by-step explanation:
3(5)=15
therefore,
15-7=8
<3
Answer:
It should be 245 m
Step-by-step explanation:
Separate it like this:
chop of the rectangle part and find the area of that and then add it to the trapezoid part
10*20 = 200.
Area of a trapezoid = 5+10/2 *6.
5+10 = 15. 1
5/2 = 7.5.
7.5*6 = 45.
45 + 200 = 245
Answer:
6.625 inches or 6 5/8 inches
and the drop down hopefully will let you choose "between 6 and 7 inches"
Step-by-step explanation:
53/8 = 6.625
0.625 = 5/8
Let me know if you have questions about this. Have a good night.
