A spaceship ferrying workers to Moon Base I takes a straight-line path from the earth to the moon, a distance of 384,000km. Suppose the spaceship starts from rest and accelerates at 20.0 m/s^2 for the first 15.0 min of the trip, and then travels at constant speeduntil the last 15.0 min, when it slows down at a rate of 20.0 m/s^2 , just coming to rest as it reaches the moon. (a) What fraction of the total distance is traveled at constant speed? (b) What total time is required for the trip?

Hi I am in phyiscs I and it has the problem a runner ran the marathon (approx. 26.1) in 2 hours and 57 min. What was the average speed of the runner in m/s? I understand that I would have to divide the total distance by the total time, but I'm not sure how they changed the miles to meters. Please break it down so I can understand. I tried to solve it how you guys did it but I keep getting another answer. Thank you!
why do we use meters “per” second when calculating speed?
Suppose that a world-class long jumper jumped on the moon with the same initial velocity as that which would produce a world record breaking distance of 10.5 m on earth. What would be the range of this lunar long jump? Gravitational acceleration on the moon is 1.67 m/s2.
Hi I am in physics 1 and I need help with this problem. It saids a boy runs in an open field. He runs 233m due north in 77 seconds, turns 90 degrees to his left and runs 178m in 93 seconds. Sketch a map of his motion and find the following quantities of his motion during this period from starting time to final time a) Map of his motion b) The total distance he runs (233m + 178m= 411m) c) The displacement from starting position to final position. What I have thus far is I got c=sqrt (233)^2+(178)^2=293m. Would I subtract this number from the total distance? Please includes detailed steps of how to solve this
