Acar accelerates uniformly from +10.0 m/s to +40.0 m/s over a distance of 125 m. how long did it take to go that distance? show all your work, including the equation used, given and unknown quantities, and any algebra required. make sure your answer has the correct number of significant figures.

Initially, a particle is moving at 5.33 m/s at an angle of 37.9° above the horizontal. two seconds later, its velocity is 6.11 m/s at an angle of 54.2° below the horizontal. what was the particle's average acceleration during these 2.00 seconds in the x-direction (enter first) and the y-direction?
