PS 4.2
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 x 103 m/,2)t² – (8.0 x 104 m/,3) t³ . The object
leaves the end of the barrel at t = 0.025 s. What net force must be exerted on a 1.50-
kg object at (i) t = 0 and (ii) t = 0.025 s?
