Answer:
the final speed of object A changed by a factor of = 0.58
the final speed of object B changed by a factor of = 1.29
Explanation:
Given;
kinetic energy of object A, = 27 J
let the mass of object A =
then, the mass of object B =
work done on object A = -18 J
work done on object B = -18 J
let be the initial speed
let be the final speed
For object A;
Thus, the final speed of object A changed by a factor of = 0.58
To obtain the change in the final speed of object B, apply the following equations.
Thus, the final speed of object B changed by a factor of = 1.29
Answer:
Leak 1 = 3.43 m/s
Leak 2 = 2.42 m/s
Explanation:
Given that the top of the boot is 0.3 m higher than the leaks.
Let height H = 0.3m and the acceleration due to gravity g = 9.8 m/s^2
From the figure, the angle of the leak 1 will be approximately equal to 45 degrees. While the leak two can be at 90 degrees.
Using the third equation of motion under gravity, we can calculate the velocity of leak 1 and 2
