Question
you throw a rock off off a cliff in the horizontal direction with a velocity, v, One second later you throw an identical rock with the same velocity, v, in the horizontal direction.
(10%) Problem 3: You throw a rock off of a cliff in the horizontal direction with a velocity, v. One second later you throw an identical rock with the same velocity, v, in the horizontal direction. What is true about the distance between the two rocks beginning after you throw the second one? Whether the distance between the rocks will increase or decrease depends on the velocity v with which they are thrown It cannot be determined. °The distance between the rocks will stay the same as time passes. It depends on the height of the cliff. The distance between the rocks will decrease as time passes The distance between the rocks will increase as time passes Submit Feedback I give up!Explanation / Answer
Expression for displacement:
S = vo t + (1/2 ) gt^2
Here, vo is initial velocity, t is time , g is accleration due to gravity
Here, the horizontal component is unchanged; vertical velocity changes
As the initial speed is zero, the above equation
S = (1/2 ) gt^2
As the time passes, the distance between rocks varies with square of the time ( t 2) and g is always constant.
Therefore, the separation between the rocks increases as time passes.
Correct option is
The distance between the rocks will increase as time passes ( Last option is correct )
