Answer:
0m/s²
Explanation:
Given parameters:
Initial velocity of the boat = 8m/s
Final velocity = 8m/s
Time taken = 4s
Unknown:
Acceleration of the boat = ?
Solution:
Acceleration is the rate of change of velocity with time.
It is mathematically expressed as;
A =
A is the acceleration
v is the final velocity
u is the initial velocity
t is the time taken
Insert the parameters and solve;
A = = 0m/s²

Answer:
a
The speed of wave is
b
The new speed of the two waves is
Explanation:
From the question we are told that
The mass of the string is
The length is
The tension is
Now the velocity of the first wave is mathematically represented as
Where is the linear density which is mathematically represented as
substituting values
So
Now given that the Tension, mass and length are constant the velocity of the second wave will same as that of first wave (reference PHYS 1100 )
