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 ×10^3 m / s^2) t^2-(8.0 ×10^4 m / s^3) t^3 . 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 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? | Numerade
