Calculating Distance and Velocity in Two-Dimensional Kinematics

AI Thread Summary
To solve the problem of an airplane releasing a package, first calculate the time it takes for the package to fall 585 m, using the equation for free fall. Then, determine the horizontal distance traveled by multiplying the time by the airplane's forward speed, which is derived using trigonometry. For the angle of the velocity vector just before impact, apply trigonometric principles to combine the vertical and horizontal components of the package's velocity. The final results indicate the package lands 1040 m from the release point and impacts at an angle of -61.0°. Understanding these calculations is essential for mastering two-dimensional kinematics.

Ive been trying to get this problem. I already have the answers but I want to know how to solve it.

An airplane with a speed of 77.5 m/s is climbing upward at an angle of 34.1 ° with respect to the horizontal. When the plane's altitude is 585 m, the pilot releases a package. (a) Calculate the distance along the ground, measured from a point directly beneath the point of release, to where the package hits the earth. (b) Relative to the ground, determine the angle of the velocity vector of the package just before impact.

The answers are:
(a)1040 m
(b)-61.0°

Can someone help me?

what have you done so far??
 
goj2: a) work out how long the package will take to fall 585m. Then multiply the answer by the forward speed of the aircraft, worked out using trigonometry. b) is more trigonometry based on the forward speed and the vertical speed.

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
