Required information The cutaway of the gun barrel shows a projectile moving through the barrel. The projectile's exit speed is vs = 1675 m/s (relative to the barrel), the projectile's mass is 18.5 kg, the length of the barrel is L = 4.4 m, the acceleration of the projectile down the gun barrel is constant, and Ⓡ is increasing at a constant rate of 0.18 rad/s. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. L Determine the pressure force acting on the back of the projectile. It is given that = 20°. (Round the final answer to four decimal places.) The pressure force on the projectile is 31.8882 × 106 N.

1 Problem = Let I = {0,11,12,13} be an inertial reference frame from which the position of a particle is measured. At initial time to = 0 a particle is at rest in the x - y plane at coordinates (xo, yo) = (6,0) in units of inches (where x is the component along the 2₁ direction and y is the component along the 22 direction). If the particle is then subjected to the acceleration components ax(t) 0.5-0.35t in/sec² and ay 0.15 0.02t2 in/sec². What is the vector describing the particle's position when t = 6? = =

WORKSHEET: A racing car starts at rest at point A and increases its speed around the track at a constant rate of 6 ft/sec², traveling counterclockwise. Determine the position and the time at which the car's acceleration magnitude reaches 20 ft/sec². y ↑ 200 ft Used with permission from "Engineering Mechanics: Dynamics." McGill/King, 4th Ed, 2003

A vehicle moving horizontally gets a load of wind resistance acting in the opposite direction to the vehicle's motion F M cv? v is the horizontal speed of the vehicle. F is the thrust that comes from the vehicle engine c damping coefficient for wind resistance force (c =0.20 N.sec2/m2) M is the mass of the vehicle (M = 1000 kg) Using Newton's 2nd law, we get the equation of motion dv 1000- + 0,2 v² = F dt At steady state the speed of the car is vo = 30 m/s and thrust F, = 0.2 v3 = 180 N. If the car is moving at a speed around steady state v = vo + dv = 180 and F = F, + 8F, derive a linear differential equation connecting d(dv) ,8v and SF. dt

0.8 m wo B D E 0.8 m 1.0 m Bar AB rotates about the fixed point A with constant angular velocity wo. The system starts with bar AB horizontal. 1) Use the relative velocity equation to find the velocity of C in terms of the angles 0 and > and their derivatives. 2) Determine the lengths of bars AB and BC so that as bar AB rotates, the collar C moves back and forth between the positions D and E. A design constraint is that bar BC must be longer than bar AB (as shown in sketch). 3) You are given the design constraint that the magnitude of the acceleration of collar C must not exceed 200 m/s². What is the maximum allowable value of wo? 4) Create the following plots for a complete revolution of bar AB using the values for lengths and angular velocity determined above: о о e and > versus time as 2 sub-plots. Position, velocity, and acceleration of C versus time as 3 sub-plots. Velocity and acceleration of C versus its position as 2 sub-plots. - 5) Use your plotted results to describe the…
