Engineers are developing new types of guns that might someday be used to launch satellites as if they were bullets. One such gun can give a small object a velocity of 4.1 km/s, moving it through only 1.6 cm.
1. What acceleration does the gun give this object?
2.Over what time interval does the acceleration take place?
and what does µ mean?
a) use vf^2=v0^2+2ad
where vf=final speed = 4100 m/s
v0=initial speed =0
a = acceleration
d=distance traveled = 0.016 m
a=4100^2/2(0.016) = 525,312.5 m/s/s
b) acceleration = change in speed/time
time = change in speed/accel
time = (4100m/s-0)/5.25x10^5m/s/s = 7.8x10^(-3) s
u can mean several things in science
as a prefix in a unit, it means micro, or one millionth, so um is a micrometer or a millionth of a meter
it can also represent coefficient of friction
it can also represent the subatomic particle called the muon, but I am guessing it is not that in this case
hope this helps
