Answer:
A. 216.36 
B. 96.56
Explanation:
Let 
be the distance in first part.
= velocity × time
= 85 × 
= 49.58 km
Let 
be the distance in first part.
= 130 km
Average velocity = 
When second leg of the trip is
A. Toward north
Average velocity = ![\frac{[tex] s_{1} + s_{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%5Btex%5D%20s_%7B1%7D%20%2B%20s_%7B2%7D%20%20%20)
}{Total time} [/tex]
Average velocity = 
Average velocity =216.36
B. Toward south
Average velocity = ![\frac{[tex] s_{1} - s_{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%5Btex%5D%20s_%7B1%7D%20-%20s_%7B2%7D%20%20%20)
}{Total time} [/tex]
Average velocity = 
Average velocity =96.56
Answer:
Each force acting on the blob has another one to cancel it out
Explanation:
The speed of a 16cm wave with a period of 8 seconds is 2cm/s
<h3>How to determine the speed</h3>
Using the formula;
Speed = distance ÷ time
Distance = 16cm
time = 8 seconds
Substitute into the formula
Speed = 16 ÷ 8
Speed = 2 cm/s
Therefore, the speed of a 16cm wave with a period of 8 seconds is 2cm/s

Answer:
Ft
Explanation:
We are given that
Initial velocity=u=0
We have to find the magnitude of p of the momentum of the particle at time t.
Let mass of particle=m
Applied force=F
Acceleration, 
Final velocity , 
Substitute the values
We know that
Momentum, p=mv
Using the formula
