A car picking up speed at a uniform rate from rest passes three VECO posts in succession. The posts are 91 meters apart along the road. The car takes 10 seconds from the first to the second post, and 6 seconds from the second to the third post. Calculate:
a. the acceleration of the car
b. the distance from the starting point of the car to the first post
c. the car’s velocity at each post.

Question

A car picking up speed at a uniform rate from rest passes three VECO posts in succession. The posts are 91 meters apart along the road. The car takes 10 seconds from the first to the second post, and 6 seconds from the second to the third post. Calculate:
	a.	the acceleration of the car
	b.	the distance from the starting point of the car to the first post
	c.	the car’s velocity at each post.

darkknight · Answer

so acceleration is a constant value, 10 secs from the first to the second post,
we are given the posts are 91 meters apart. You can find the velocity by doing distance (91 meters) divided by the time it took to get to each post : part c
