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?

A ball is thrown upwards with a speed of 20 m/s off a 5-meter-high balcony. How fast is it falling just before it hits the floor below the balcony? We want to show that the answer does not depend on whether we choose +y to be up or to be down. When an object is in free-fall, its acceleration is g=10 m/s²2 down. а. Take +y to be up. VWhat are the values of voy,ay and Ay in this case? b. Take +y to be down. What are the values of voy, avy, and Ay in this case? Only one of the constant acceleration kinematics equations do not involve time. vž = vžy +2 a,Ay. Solve for С. %3D the speed |vl just before the ball hits the floor using +y up and using +y down and show you get the same answer.
