A small projectile (caliber, 9 mm) is fired vertically downward into a fluid medium with an initial velocity of 500 m/s. Due to the resistance of the fluid the projectile experiences a deceleration equal to a --0.6 v' m/s2, where v is in m/s. Determine the projectile's velocity 4 seconds after it is fired. You may neglect gravity! (2 points) 0

A projectile is fired downward with initial speed
v0 in an experimental fluid and experiences an
acceleration a = σ - ηv2,
where σ and η are positive constants and
v is the projectile speed. Determine the distance
y traveled by the projectile when its speed has been
reduced to 0.58v0. Also, determine the terminal
velocity vf of the projectile. Evaluate for
σ = 1.10 m/s2, η = 0.17
m-1, and v0 = 4.8 m/s.

1. If a projectile is fired with an initial velocity of vo meters per second at...
If a projectile is fired with an initial velocity of v0 meters per second at an angle α above the horizontal, and air resistance is assumed to be negligible, then its position after t seconds is given by the parametric equationsx=(v0 cos α) t y=(v0 sin α) t-1/2 g t2where g is the acceleration due to gravity (9.8 m / s2)(a) If a projectile is fired with α=45° and v0=900 m / s, when will it hit the ground? How...

Problem 4: A projectile is fired with an initial velocity of 54.1 m/s, at an initial inclination of 33.7 degrees with the horizontal r-axis. All initial variables (displacement and time) start at 0. You are asked to consider two cases of motion for the projectile, one without drag, and one with drag, with both the cases including effects of gravity. a) For motion with no drag, acceleration vector is given as а -g, where g 9.8 m/s. b) For motion...

8. A projectile is fired from the origin in a straight line towards a rectangular target and hits it perpendicularly 2 seconds later. The vertices of the rectangle are (50,100,275), (100, 0, 275), (200,50, 150), and (150, 150, 150), where units are in meters. (a) At what point did the projectile hit the rectangle? (b) The projectile was trying to hit the center of the target. How accurate was it? (c) Assuming the projectile was moving at a constant speed,...
