Since the kayakers speed is 1.5 meters per second relative to the stream, the kayakers velocity in meters per second relative to the shore should be its speed relative to the stream plus the stream's velocity relative to the shore. This is 1.5m/s + 3.0m/s which is equal to 4.5 meters per second (m/s).
The kayaker's speed relative to the shore is calculated by adding the stream's speed (3.0 m/s) and the kayaker's speed relative to the stream (1.5 m/s), which results in 4.5 m/s.
In this scenario, the kayaker's total velocity, or speed relative to the shore, is the vector sum of the kayak's velocity relative to the water and the water's velocity relative to the shore. This principle reflects how velocities combine in Newtonian mechanics. Given that the stream's velocity is 3.0 meters per second and the kayaker's velocity relative to the stream is 1.5 meters per second, we add these velocities together to get the kayaker's velocity relative to the shore.
Therefore, the kayaker's speed relative to the shore is 4.5 meters per second. This sum is based on the principle that when moving downstream, the stream's velocity (its speed in a particular direction) augments the velocity of the kayak.

Answer:
45 meters
Explanation:
notice that is you multiply the time with the speed the units cancel to get distance.
therefore
distance=velocity(time)
distance=(3)15
distance =45 meters

Answer:
1. the speed is constant
2. the average speed is .5 m/s
Explanation:
I have attached a graph of the data in excel.
from excel i got the equation of the line to be y=.5x with y being distance and x being time.
the function is a position function so if you take the derivative of it you get the velocity which is .5.
since the derivative is a constant the the speed does not change and the average velocity is the derivative.
A. zoning laws
B. immigration reforms
C. international treaties
D. the amount of money in circulation
Answer:
B
Explanation:
Answer:
The object is sitting
Explanation:
Therefore the object cannot be in current motion as no force has been acted upon it (exept gravitational force)
by 68.0°C. What is the mass of the coin?
Please helppp!!!
The mass of the copper coin placed in 101g of water is 135.3g.
The mass of the copper coin can be calculated using the following expression:
Since; Q = mc∆T
Where;
According to the question;
COPPER METAL:
WATER:
m = 101g
c = 4.18 J/g°C
∆T = 8.39°C
⇒ 101 × 4.18 × 8.39 = (0.385 × m × 68)
⇒ 3542.09 = 26.18m
⇒ m = 3542.09 ÷ 26.18
⇒ m = 135.3g
Therefore, the mass of the copper coin placed in 101g of water is 135.3g.
