a second astronaut did another experiment in space. she attached a small rocket to the same ball to continuously push the ball the entire distance. it also traveled 50meters from the space station (point a) to the space ship (point d), in space. astronaut 1 measured the speed at point b to be 0.25 m/s. astronaut 2 measured the speed at point c to be 0.75 m/s. the total amount of time required for the ball to travel the 50 meters from the space station to the space ship was 1 minute 22 seconds. what was the acceleration? (hint: convert the time to seconds! )
