Answer:
the amplitude of the subsequent oscillations is 0.11 m
the period of the subsequent oscillations is 1.94 s
Explanation:
given Information:
the mass of air-track glider, = 750 g = 0.75 kg
spring constant, k = 13.0 N/m
the mass of glider, = 200 g = 0.2 kg
the speed of glider, = 170 cm/s = 1.7 m/s
the amplitude of the subsequent oscillations is A = 0.11 m
according to mechanical enery equation, we have
where
A is the amplitude and is the final speed.
to find , we can use momentum conservation lwa, where the initial momentum is equal to the final momentum.
= 0, thus
(0.75+0.2) = (0.75)(0)+(0.2)(1.7)
0.95 = 0.34
= 0.36 m/s
Now we can calculate the amplitude
A = 0.11 m
the period of the subsequent oscillations is T = 1.94 s
the equation for period is
T = 2π
T = 2π
T = 1.94 s
The distance is 20 miles
Explanation:
Definitions:
- Distance is the total length of the path covered by an object during its motion, regardless of the direction of its motion
- Displacement is the shortest distance between the initial and final position of the motion, so it also takes into account the direction of motion
In this problem, we want to know the distance covered by the woman. The motion consists of the following parts:
north
east
south
To find the distance, we just have to add the length of each path, ignoring the direction. Therefore:
