A few seconds after a plane took off it was hit by a missile launched from a distance on the ground. The path of the plane is described by y=(0.0005 x?)m. The missile traveled along a parabolic path described by y2 = (160 x), where the coordinates are measured in meters. If the components of the missile velocity in the horizontal and vertical directions are constant at vx =120 m/s and v; = 100 m/s, respectively, and the plane was...
When a rocket reaches an altitude of 40 m it begins to travel along the parabolic path (y- 40) 160 x, where the coordinates are measured in meters. If the component of velocity in the vertical direction is constant at vy 180 m/s, determine the magnitudes of the rocket's velocity and acceleration when it reaches an altitude of 80 m. 40)2 160x 40 m
using chain rule method 1. For a short time, the path of the plane is described by -20m. If the plane is rising with a constant velocity of 20 m/s, determine the magnitudes of the velocity and acceleration of the plane when it is at y 200 m
Consider again the cannonball launched by a cannon from the top of a very high cliff. Suppose that the cannonball is launched horizontally with no upward angle whatsoever and with an initial speed of 20 m/s. If there were no gravity, the cannonball would continue in motion at 20 m/s in the horizontal direction. Yet in actuality, gravity causes the cannonball to accelerate downwards at a rate of 9.8 m/s/s. This means that the vertical velocity is changing by 9.8...
----------> (I must show all work)A tennis ball is thrown upward at an angle from point A. It follows a parabolic trajectory and hits the ground at point D. At the instant shown, the ball is at pointB. Point C represents the highest position of the ball above the ground.While in flight, how do the x and y components of the velocity vector of the ball compare at the points A and D?A) The velocity components are non-zero at A...
Ground-based air defence systems play an important part in ensuring the safety and security against any possible attacks from the air. For example, a few of such systems were deployed during the Trump-Kim summit held in Singapore on 12 June this year. As shown in Figure 2(a), a particular air defence system consists of an interceptor missile that can be launched from a Mobile Firing Unit (MFU). Actual systems will require very precise engineering involving interceptor missiles that can lock...

A projectile is launched from level ground at an angle of 30 degrees to the horizontal. If the magnitude of the launch velocity is 30 m/s, calculate the time rate of change in speed and radius of curvature when t=1, 2, and when the projectile is at its max height. Please do the problem how the description says to do it below and put the answer neatly in a table format. Thank you. 2) A projectile is launched from level...
I. A projectile is launched from point A with an initial velocity of vo and an elevation angle θ as shown. The air resistance is neglected and gravitational acceleration is constant. a) Show that the equation of the path is y-2v zg+x tan θ, where g is the gravitational 2 2v6cos20 acceleration b) Determine the radius of curvature of the path in terms of the time t using n-t coordinate system c) For Vo-10 m/s and θ-40°, plot the radius...
