Answer is d 30 m/s, North
Given: Distance d = 60 m; Time t = 2 seconds
Required: Average Velocity Vave. Vi + Vf/2
Formula: d = 1/2 at² derive acceleration a = ? and a = Vf - Vi/t
a = 2d/t²
a = 1/2(60 m)/( 2 s)²
a = 30 m/s²
Solve for final Velocity Vf = ?
a = Vf -Vi/t
Vf = at Since Initial Velocity is zero
Vf = (30 m/s²)(2 s)
Vf = 60 S
For average velocity Vave. = Vi + Vf/2
Vave. 0 + 60 m/s/2
Vave = 30 m/s North.
Answer:
I would say a pond
Explanation:
A pond is more still than an ocean, therefore you could see your reflection better
