Heres are the problems:

1. --If one object has a greater speed than a second object, does the first necessarily have a greater acceleration? Explain, using examples.

2.--Can the velocity of an object be negative when its acceleration is positive? What about visa versa?

3.--A car slows down from 20m/s to rest in a distance of 85m. What was its acceleration, assumed constant?

4.--at highway speeds, a particular automobile is capable of an acceleration of about 1.6m/s. At this rate, how long does it take to accelerate from 80km/h to 110km/h?

Id greatly appreciate it if you can answer any of these problems.

Find two values which satisfy the following:

Square pyramid number + 1 = Tetrahedral number

(Square pyramid numbers are made up of consecutive squares, i.e. 1 + 4 + 9 + 16... for each layer of the pyramid. Tetrahedral numbers are made up of consecutive triangular numbers, i.e. 1 + 3 + 6 +10 +15... for each layer of the triangle-based pyramid.)

One of the answers is 55 and 56. What is the other??
