1) 3 miles/Hour
The speed is defined as the distance covered divided by the time taken:
where
d = 1.5 mi is the distance
t = 0.5 h is the time taken
Substituting,
2) 1.34 m/s south
Velocity, instead, is a vector, so it has both a magnitude and a direction. We have:
is the displacement in meters
is the time taken in seconds
Substituting,
And the direction of the velocity is the same as the displacement, so it is south.
Answer:
23932242.5 Pa
Explanation:
= Atmospheric pressure =
= Pressure of seawater
= Density of sea water =
h = Depth of shipwreck =
g = Acceleration due to gravity = 9.81 m/s²
The absolute pressure is given by
The absolute pressure at the depth of the shipwreck is 23932242.5 Pa
The position of the mass is given by (in cm):
The velocity is the derivative of the position:
Substituting t=0.40 s, we can find the velocity at this time:
The velocity is the derivative of the position:
Substituting t=0.40 s, we can find the velocity at this time:
