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 while moving it through a distance of only 2.5 cm.

Question

(a) What acceleration does the gun give this object?

(b) Over what time interval does the acceleration take place?

Answer 1

Vfinal = sqrt(2aX) = 2700 m/s
X = 0.025 m . Solve for a

Time interval = (distance)/(average speed) = .025m/1350 m/s = ____ s
