A speedboat increases its velocity from 25 m/s to the west to 35 m/s to the west in a distance of 250 m. Find the time it takes the boat to travel this distance.

If the ama of the inclined plane below is 2, calculate the ima and efficiency. ima = efficiency =

Aparticle moves in the xy plane with constant acceleration. at time zero, the particle is at x = 6 m, y = 8.5 m, and has velocity ~vo = (9 m/s) ˆı + (−2.5 m/s) ˆ . the acceleration is given by ~a = (4.5 m/s 2 ) ˆı + (3 m/s 2 ) ˆ . what is the x component of velocity after 3.5 s? answer in units of m/s.
