Answer:
Centripetal acceleration
Explanation:
- The centripetal acceleration is the motion inwards towards the center of a circular path.
- <em><u>Centripetal acceleration is given by; the square of the velocity, divided by the radius of the circular path.
</u></em>
ac = v²/r
Where; ac = acceleration, centripetal, m/s², v is the velocity, m/s and r is the radius, m
Answer:
The slope of a velocity graph represents the acceleration of the object. So, the value of the slope at a particular time represents the acceleration of the object at that instant.
during satellite motion we know that total energy is always conserved
so here we will have

here we know that


now at other position

now from above equation we have

now we have


so its kinetic energy will be 3500 MJ
The dummy's acceleration is 11 m/s^2
(also known as 11 meters per sec. per sec.)
a = F/m
= 825 N/75 kg
= 11 m/s^2
Given:
450 grams of water (Tw = 24 C)
Thermal capacity of the beaker = negligible
Q = 0
Tice = 0 C
Tfinal = 8 C
450g * (Tf - Tw) + m_ice * (Tice - Tw) = 0
450g * (8 - 24) + m_ice (0 - 24) = 0
solve for m_ice
