Freight trains can produce only relatively small acceleration and decelerations. (a) What is the final velocity (in m/s) of a freight train that accelerates at a rate of 0.0700 m/s for 8.00 min, starting with an initial velocity of 4.00 m/s? m/s (b) If the train can slow down at a rate of 0.450 m/s2, how long (in s) will it take to come to a stop from this velocity? (c) How far (in m) will it travel in each...

6) A train starts from rest and accelerates uniformly, until it has traveled 5.4 km and acquired a 6) velocity of 31 m/s. The train then moves at a constant velocity of 31 m/s for 400 s. The train thern decelerates uniformly at 0.065 m/s2, until it is brought to a halt. The distance traveled by the train during deceleration, in km, is closest to: A) 6.0 B) 7.0 C) 6.7 D) 63 E) 7.4 Situation 2.2 A rock...

20125982 ANALYZE (A) Determine how the velocity varles for positive acceleration and initial velocity to the right. The acceleration vs. time plot for constant acceleration is a straight line parallel to the time axls. It lles above the origin for acceleratlon to the right. During the acceleration, the velocity Increases by 1.6 m/s each second, so the velocity vs. time graph is a line with a slope of 1.6 m/s per second, and X m/s )+1.6 m/s2)t. The car starts...

I know there is 4 different equationsfor kinematics. Can you pick
the problems that use each one and write out how you do it?
Especially 6 and 10 because those seem very hard.
