With the above question and the ones a subway train is traveling at a rate of 22.4 m/s. brakes are applied and it slows down at a constant rate of 3.5 m/s^2 until it stops at a station. find the total distance traveled while braking. 72 m 142 m 274 m 163 m a cyclist is stopped at a traffic light. when the light turns green, the cyclist accelerates at 3.2 m/s^2. after 2.4 seconds, what is the cyclist’s speed? 15 m/s 7.7 m/s 5.6 m/s 0.75 m/s

Train: we're given the initial velocity of 22.4 m/s, told that acceleration is a constant 3.5 m/s^2, and that it eventually stops so that its final velocity is 0 m/s. The total distance can then be computed by solving

Cyclist: it starts at rest, so is 0 m/s, then it accelerate at a cosntant 3.2 m/s^2, and we're told it does so for 2.4 s. We can solve for via

Object: the answer they're looking for here is probably the first choice. But technically any one of these equation can be used to determine the total displacement . In order to properly use the other three you need to know the value of which can be computed with the given information, since constant acceleration means average/instantaneous accelerations are the same.
