Answer:
a
b
The value is
Explanation:
From the question we are told that
The mass is
The spring constant is
The instantaneous speed is
The position consider is x = 0.750A meters from equilibrium point
Generally from the law of energy conservation we have that
The kinetic energy induced by the hammer = The energy stored in the spring
So
Here a is the amplitude of the subsequent oscillations
=>
=>
=>
Generally from the law of energy conservation we have that
The kinetic energy by the hammer = The energy stored in the spring at the point considered + The kinetic energy at the considered point
=>
=>
Answer:
8750 miles
Explanation:
The airplane travels with uniform motion (=constant velocity), so we can calculate the distance it travels using the formula for uniform motion:
where
v is the speed of the plane
t is the time elapsed
In this problem:
v = 5000 mi/h is the speed of the plane
t = 1 h 45 min is the time elapsed
We have to convert this time into hours; we know that 45 minutes corresponds to 3/4 of an hour, that is 0.75 hours. So, the time here is
Therefore, the distance covered is:
