(a)
use v²-u²=2aS
where
S=distance
a=acceleration
v=final velocity
u=initial velocity
Solve for a.
Be sure to use consistent units.
(b)
v=u+at
where t=time,
solve for t.
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 2.5 km/s while moving it through a distance of only 1.7 cm.
(a) What acceleration does the gun give this object?
(b) Over what time interval does the acceleration take place?
