Projectile motion radar antenna

Click For Summary
SUMMARY

The discussion focuses on calculating the x and y components of a satellite's position as tracked by a radar antenna. The radar antenna is positioned 162 km away from the satellite at an angle of 62.3 degrees from the ground. The solution involves using trigonometric functions to resolve the position into its components, specifically applying the equations V0y = Vo (cos) angle and Vx = Vo (cos) angle. A diagram is recommended to visualize the right-angled triangle formed by the satellite's position.

PREREQUISITES
  • Understanding of trigonometric functions, specifically sine and cosine.
  • Familiarity with the concept of right-angled triangles.
  • Basic knowledge of radar technology and its applications in tracking.
  • Ability to manipulate equations involving distance and angles.
NEXT STEPS
  • Study trigonometric identities and their applications in physics.
  • Learn about radar systems and their operational principles.
  • Explore vector decomposition in physics for more complex motion analysis.
  • Practice solving problems involving projectile motion and satellite tracking.
USEFUL FOR

Students in physics, engineers working with radar technology, and anyone interested in satellite tracking and motion analysis will benefit from this discussion.

Homework Statement



A radar antenna is tracking a satellite orbiting the earth. At a certain time, the radar screen shows the satellite to be 162 km away. The radar antenna is pointing upward at an angle of 62.3 degrees from the ground. Find the x and y component(in km) of the position of the satellite.

Homework Equations



Vx=dx/t ..... a=Vy-V0y/t ... Vy+V0y/2 = dy/t

The Attempt at a Solution



its a simple question but I am thinking too hard

V0y=Vo (cos) angle
Vx= Vo(cos) angle
dx?

Its just working out the lengths of two sides of a right angled triangle given the hypotenuse and angle. Draw a diagram of the situation and it will probably be a bit clearer.
