I just wanted to double check on my answers here. I have all the problems posted below with my work. If you could make sure I'm doing these right I would greatly appreciate it.
A truck passes a point A on a straight level road with a constant velocity of 10 m s-1. At the same instant, an automobile starts from rest at point A and travels in the same direction as the truck, with a constant acceleration of 1.6 m s-2.
A) How long a time does the automobile take to pass the truck, from the instant it starts at point A?
B) How far beyond the starting point will the automobile overtake the truck?
C) Determine the average speed of the bus during the interval, t=0 to t=10 s.
D) How fast will the automobile be traveling, when it passes the truck?
E) If the speed limit on this road is 50 km/hr., is the automobile within the speed limit as it passes the truck?
My work is attached below. I did a problem similar to this and found that the answer for my time was half what it should have been.This messed up all my other answers. I'm not sure where I'm making my mistake in finding the time.
