Projectile motion radar antenna

AI Thread Summary
To determine the x and y components of the satellite's position, the radar antenna's angle of 62.3 degrees and the distance of 162 km are used to form a right triangle. The x component (horizontal distance) can be calculated using the cosine function, while the y component (vertical distance) uses the sine function. The formulas Vx = Vo(cos(angle)) and Vy = Vo(sin(angle)) apply here, where Vo is the hypotenuse (162 km). A diagram can aid in visualizing the relationship between the components. This approach simplifies the problem by breaking it down into manageable parts.

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.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
