An electric skateboarder is travelling west on a path along the river at 5m/s. Å brisk walker on the other side of the riverbank is walking east along a path at 3m/s. The two paths are 40m apart. The skateboarder is initially 600m east of the walker. After 60 seconds, how fast is the distance between the skateboarder and the walker changing? Note: We encourage you to use a scientific calculator for this question. The answer below was rounded to 4 decimal points. 1.6873m/s -5.4891m/s O-7.5895m/s -9.3214m/s

The figure here shows the speed v versus height y of a ball tossed directly upward, along a y axis. Distance d is 0.37 m. The speed at height yA is vA. The speed at height yB is vA/3. What is speed vA?
There are more than 1/4 million species of beetle. Assume the average length of a beetle is 1cm and the average walking speed is 10 cm per second. These beetles walk up a gang-plank that is 5 meters long onto an ark. They do this in pairs, side by side, one male and one female from each species. The pairs of beetles are spaced 8 cm apart. How many hours will it take for 1/4 million species of beetles to embark onto the ark once the first pair starts up the gangplank?
Here we go again (yes, this set of questions is starting to feel like Groundhog Day). You AGAIN wake up in a strange room, and this time you drop a ball from a height of 2.10 m, and observe that it hits the floor 0.393 s after you drop it. In this case you suspect you are in deep space, far from any planet or star, and that your rocket is accelerating due to the push of its own engines under the floor. In this case, what must the acceleration of your rocket be? Question 3 options: 13.6 m/s^2 20.4 m/s^2 46.2 m/s^2 27.2 m/s^2
Please answer the question, I will thumbs up. read the problem and answer the three questions. This is for physics
A bunch of keys was thrown directly upward by Macoy, who is looking out of the window, to be caught by Len-Len living on a room right above him. Unfortunately, Len-Len wasn't able to catch the keys and therefore the bunch of keys went straight to the ground. If Macoy gave the keys an upward speed of 3 m/s and the keys reached the ground after Macoy threw the keys upward in 4 seconds, a. What is the speed of the keys just before it reached the ground? b. How high is his room from the ground? c. What is the keys' acceleration when it reached its highest point? d. What is the keys' velocity when it reached its highest point? THANK YOU FOR THE ANSWER FOR A AND B. NOW CAN U ANSWER C AND D? THANKS
Suppose you are watching the destruction of a bridge. The bridge is blown up and the sounds of the explosion reaches you in 3 seconds. How far away from the bridge were you standing? Assume the speed of the sound is 344 m/s for this question.
Jane is driving down the road at 20.0 m/s looking for a house address. when she sees the house, she slams on her brakes. If her reaction time is 1.20s and her car deaccelerates at 3.50 m/s^2, how far past the point where she first saw the house did her car come to rest? I feel like I need to use one of the 4 kinematics equations, but none seem to be giving me the correct answer when I plug in my numbers :(
A moving walkway at an airport has a speed v1 1 and a length L. A woman stands on the walkway as it moves from one end to the other, while a man in a hurry to reach his flight walks on the walkway with a speed of v2 relative to the moving walkway. (a) How long does it take the woman to travel the distance L? (b) How long does it take the man to travel this distance?
So this is the problem I am trying to figure out: A boy tosses a coin straight up to 2.2 m. Suppose the height when the coin leaves his hand is 1.3 m. What was the initial speed of the coin when it left his hand?
A biker is moving along a road at a uniform velocity of 5 m/s. A second biker is moving along the road at a uniform velocity of 8 m/s in the same direction, and overtakes the first biker. From the second biker's perspective, what is the relative velocity of the first biker? -3 m/s - 5 m/s 11 m/s 3 m/s
OK, this is the last time for one of these crazy adventures. THIS time, though, there is a window in the floor, and you can see that you re in a rocket which has just taken off from the surface of an alien planet. By taking careful measurements out that window you determine that the rocket is accelerating upward at 8.29 m/s^2. When you drop a ball from a height of 2.08 m, it hits the floor 0.207 s later. What is the value of g for the alien world below you? 97.9 m/s^2 168.7 m/s^2 88.8 m/s^2 106.9 m/s^2
A rocket is launched from a height of 3 m with an initial velocity of 15 m/s. At what time will the rocket be 13 m from the ground?
