Question

to study damage to the 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 (10.0x10^3 m/s^2)t^2 + (4.0x10^4 m/s^2)t^3. The object leaves the end of the barrel at t = 1.0 second. what is acceleration for an object in the gun barrel at time t=1.0 second? -this question to solve (What net force, in unit of Newton, must be exerted on a 2.0-kg object at t = 1.0 second?) a. less than 300,000 b. Between 300,000 to 400,000 c. more than 400,000. d. none of the above.
