Impulse = Ft = (m)(delta v)
delta v = change in velocity = velocity final - velocity initial.
= -22m/s - +18m/s = -40m/s.
mdeltav = (0.40kg)(-40m/s) = -16kgm/s or -16Ns.
Designing warning and evacuation systems could be a step in a plan designed to mitigate the negative impacts of a natural hazard.
frequency is how many times a sec the thing vibrates
amp is the size of the vibration
wavelength is distance peak to peak for example
Answer:
Gravity
Explanation:
The Hubble is continually attracted to the earth due to the action of gravity. Therefore, it is thanks to gravity that the space telescope is kept in orbit. Without him, the direct motion generated by inertia would take him out of course. Gravity slows it down and keeps it in the curved path of its orbit around the Earth.
