A small projectile is fired vertically downward into a fluid medium with an initial velocity of 60 m/s. Due to the drag resistance of the fluid the projectile experiences a deceleration of a (-0.4) m/s2, where v is in m/s. Determine the projectile's velocity and position 4 s after it is fired.
2.2 INTEGRALS OF VECTOR FUNCTIONS; PROJECTILE AND CIRCULAR MOTION 4. A projectile is fired northward out to the sea from the top of a cliff 264 ft high. Assuming that the r-axis is pointing east and y-axis is pointing north. The projectile's initial velocity vector is v(0) experiences in flight an eastward acceleration of 3 ft/s2 due to spin. Find the projectile's velocity and position vectors t seconds after the projectile is fired. (0, 92, 14). In addition to a...
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. VYUO

A projectile, initially at the origin, moves along a straight-line path through a fluid medium such that its velocity is v=1800(1−e−0.3t)mm/s where t is in seconds. Determine the displacement of the projectile during the first 2 s .
If a projectile is fired with an initial velocity of vo meters per second at an angle a above the horizontal and air resistance is assumed to be negligible, then its position after t seconds is given by the parametric equations x = (vo cos(a)t y = (vo sin(a)t - +- 1012 where g is the acceleration due to gravity (9.8 m/s2). (Round your answers to the nearest whole number.) (a) If a gun is fired with a = 30°...
