Low frequency, low amplitude, or both.
I believe its 17,000 blood cells in your body
Answer:
11 m/s
Explanation:
The motion of the box is a uniformly accelerated motion (=constant acceleration), therefore we can use the following suvat equation:
where:
v is the final velocity
u is the initial velocity
a is the acceleration
t is the time
For the box in this problem, we have:
u = 3 m/s is the initial velocity
is the acceleration
t = 4 s is the time interval
Solving for v, we find the velocity after 4 seconds:
Explanation:
First, we need to calculate the constant force, that is, the ratio between the applied force and the rubber stretch due to the application of the force:
Now, we can know how far will an 18N force stretch the rubber. From (1):
The work done by the external force on the rubber is equal to its elastic potential energy:
Newton's second law of motion can be used to calculate weight.
