Xf=?
Xi=0m
Vi=0m/s
Vf=40m/s
a=?
t=12s
Xf=Xi+1/2(Vi+Vf)t
Xf= 0 +1/2 (0+40)12
Xf=1/2 (40)12
Xf=240m
Vf=Vi+at
40=0+a (12)
40=12a
a=3.33m/s^2
The magnet is at a gravitational force while the paper clip is at an applied force
Answer:
0.650
Explanation:
Move the decimal point three times to the left.
The initial mass fraction of the spacecraft that must be burned and ejected to achieve an increase in speed is 0,00219 m/s
<h3>What fraction of the initial mass of the spacecraft?</h3>
Increase the speed: Vf-Vi = 2.2 m/s
Speed of aircraft: Vr = 400 m/s
Speed of ejected products: Vrel = 1000 m/s
The answer is:


So, the initial mass fraction of the spacecraft that must be burned and ejected to achieve an increase in speed is 0,00219 m/s
