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/s)t°. The object leaves the end of the barrel at t = 0.025 s. Part A How long must the gun barrel be? Express your answer in meters. ANSWER: L = m Part B What will be the speed of the objects as they leave the end of the barrel? Express your answer in meters per second. ANSWER: V = m/s Part C What net force must be exerted on a 1.50-kg object at t = 0? Express your answer in newtons. ANSWER: F = N Part D What net force must be exerted on a 1.50-kg object at t = 0.025 s? Express your answer in newtons. ANSWER: F =

Our balance is maintained, at least in part, by the endolymph fluid in the inner ear. Spinning displaces this fluid, causing dizziness. Suppose a dancer (or skater) is spinning at a very fast 2.7 revolutions per second about a vertical axis through the center of his head. Although the distance varies from person to person, the inner ear is approximately 7.0 cm from the axis of spin. Y What is the radial acceleration (in m/s²) of the endolymph fluid?

Consider two spherical raindrops. The first raindrop is small with radius R1, and the second is big with radius R, = 1.5 R1. As each raindrop falls through the atmosphere, it eventually reaches its terminal velocity. Suppose the terminal velocity of the first raindrop is vr1 = 8 m/s. Calculate the terminal velocity of the second raindrop.

In the vertical jump, an Kobe Bryant starts from a crouch and jumps upward to reach as high as possible. Even the best athletes spend little more than 1.00 s in the air (their "hang time"). Treat Kobe as a particle and let ymax be his maximum height above the floor. Note: this isn't the entire story since Kobe can twist and curl up in the air, but then we can no longer treat him as a particle. Hint: Find v0 to reach y_max in terms of g and y_max and recall the velocity at y_max is zero. Then find v1 to reach y_max/2 with the same kinematic equation. The time to reach y_max is obtained from v0=g (t), and the time to reach y_max/2 is given by v1-v0= -g(t1). Now, t1 is the time to reach y_max/2, and the quantity t-t1 is the time to go from y_max/2 to y_max. You want the ratio of (t-t1)/t1 Note from Asker: I am generally confused on how to manipulate the formulas, so if you could show every step that would be great, Thank You.
