vf=at or
a= vf/time for b)
for a) vf^2=2*acceleration*distance
(2700)^2=2*acceleration*.015 solve for acceleration
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 2.7 km/s, moving it through only 1.5 cm.
(a) What acceleration does the gun give this object?
(b) Over what time interval does the acceleration take place?
