You are given a kinematics problem in two dimensions where the object is in free-fall, and it hits the ground. Which of the following is a logical choice to make when solving the problem?
| Set the final y-velocity (just before it hits the ground) to zero. |
| Set the initial x-velocity to zero. |
| Set the final y-position to zero. |
| Set the initial y-velocity to zero. |
| Set the final x-position to zero. |
Homework Answers
The ground is y - zero position, so The only logical choice is to Set the final y-position is zero. There may be other correct options like Initial x-velocity can be zero, initial y-velocity can be zero, final x-position can be zero but for all those we need additional data. So the Correct answer is Set the fianl y-position to Zero.

An object that is in free-fall has its trajectory stop when it hits a wall. Which of the following is a logical choice to make when solving the problem? Set the final y-position at the position of the wall, or set the total displacement in y equal to the vertical distance covered. Set the final y-velocity (just before it hits the wall) to zero. Set the initial x-velocity to zero. Set the final x-velocity (just before it hits the wall)...

Consider an object in free fall starting at position x_i=y_i=0 and ending up at some arbitrary final point (x_f,y_f). The initial velocity is v_i->=(v_x, v_yf)- note that the x-component of velocity is constant because we are in freefall. a)draw the free body diagram for the object. c) show that the work done by gravity is going from (0,0) to (x_f,y_f) is W=-mg delta y=-mgy_f. c)show that the change in kinetic energy is deltaK = 1/2 m(v_yi^2- v_yt^2). d)use the work-energy...

A robot probe drops a camera off the rim of a 239 m high cliff on Mars, where the free-fall acceleration is -3.7 m/s^2. a) Find the velocity with which the camera hits the ground. b) Find the time required for it to hit the ground. Ok so I'm not even sure of which equation to use for this problem. Maybe if someone just gave me a hint as to where to begin, I could get the rest...?
