To study damage to aircraft that collide with largebirds, you design a test gun that will accelerate chicken-sized objectsso that their displacement along the gun barrel is given byx = (9.0 * 103 m/s2)t2 - (8.0 * 104 m>s3)t3. The object leavesthe end of the barrel at t = 0.025 s. (a) How long must the gun barrelbe? (b) What will be the speed of the objects as they leave the end ofthe barrel? (c) What net force must be exerted on a 1.50 kg object at(i) t = 0 and (ii) t = 0.025 s?

Question
To study damage to aircraft that collide with large
birds, you design a test gun that will accelerate chicken-sized objects
so that their displacement along the gun barrel is given by
x = (9.0 * 103 m/s2)t2 - (8.0 * 104 m>s3)t3. The object leaves
the end of the barrel at t = 0.025 s. (a) How long must the gun barrel
be? (b) What will be the speed of the objects as they leave the end of
the barrel? (c) What net force must be exerted on a 1.50 kg object at
(i) t = 0 and (ii) t = 0.025 s?
