A train that is moving at a velocity of 8 m/s north begins a uniform acceleration of 0.05 m/s2 north. The acceleration is maintained through a distance of 800 m. What is the train's velocity after it has traveled the 800 m? How long does it take the train to travel the 800 m?

graph question answered .. you think better when you are relaxed and happy

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

what is the actual question though?
