To answer all questions except 15 and 19, see:
http://en.wikipedia.org/wiki/Equations_of_motion. All you need is in the section headed "SUVAT equations" and the calculations are rather simple arithmetic.
For more detail on derivations, see:

15. Average velocity (you are told it's a vector quantity. Average speed is a scalar quantity)
19. The gyroscope both translates and rotates.

locate the smallest perspective (x): x + 3x + x + seventy 5 = one hundred eighty 5x = one 0 five x = 21 answer: 21°s is the smallest perspective. information (sum of all angles is 360°s): = 21°s + 3(21°s ) + (21°s + seventy 5°) = 21°s + sixty 3°s + ninety six°s = 360°s

10. Velocity = acceleration * time = 4 * 9.81 = 39.24m/s
14. +3.0m/s (not sure)
15. Instantaneous velocity ( not sure)
18. s = 0.5 * (u+v) * t , where s=440, u = ?, v=33, t= 20
u = 11m/s
20. distance = 23 m, displacement = +1 m
25. s = ut + 0.5*a (t^2), where s=25, u =0, a=9.8, t?
25 = 0+ 4.9 (t^2)
t^2 = 5.102
t = 2.258 s
Hope it helped. :)
