had this question last night for Dr. Bob-A fox sees a piece of carrion thrown from a nest 14 m high and goes to get it. Carrion is thrown 1.5 horizontal velocity. Fox is 7. m from base of tree. What is mgnitude of fox's average velocity if it grabscarrion just as it touches ground
Answers: 1.7
3.5
4.2
2.6
Dr. Bob gave me three steps-Find time it takes to fall 14 m-which is 1/2 (9.81) times t^2=1.69
During time, how far horizontally does it goe, given horizontal velocity which is 2.52
How fast does fox have to go to cover the 7 m in falling time which is 7/1.69=4.16 which is 4.2m/s as answer
Correct or no? If not, what am I doing wrong?
Ihad 2.6 last night but that is wrong, I know it-
Please help me-my mom is getting a Physics tutor starting next Monday-Please just walk me through this problem
Thank you
Let's break down the problem step by step to find the correct answer.
Step 1: Find the time it takes for the carrion to fall 14 m.
We can use the equation for free fall: h = (1/2)gt^2, where h is the height, g is the acceleration due to gravity (9.81 m/s^2), and t is the time.
In this case, h = 14 m, so we have 14 = (1/2)(9.81)t^2.
Simplifying this equation, we can solve for t: t^2 = (2 * 14) / 9.81.
Calculating t, we get t ≈ 1.69 seconds.
Step 2: Determine how far the carrion travels horizontally during that time.
Horizontal distance = velocity (horizontal) * time.
Given that the horizontal velocity is 1.5 m/s and the time is 1.69 seconds, we can calculate the horizontal distance = 1.5 * 1.69 ≈ 2.53 meters.
Step 3: Calculate the fox's average velocity.
To cover the 7 m distance from the base of the tree to the carrion's landing point in the falling time, the fox needs to travel at an average velocity = distance / time.
The distance is 7 m, and the time is approximately 1.69 seconds (as calculated in Step 1).
So, the average velocity = 7 / 1.69 ≈ 4.14 m/s, which is closer to 4.2 m/s (the fourth answer option).
Therefore, the correct answer is 4.2 m/s, not 2.6 m/s. So your initial answer of 2.6 m/s is incorrect.
I hope this explanation helps you understand the problem better. If you have any further questions, feel free to ask!
