Solutions:
1.
d = vi*t + 0.5*a*t2 d = (0 m/s)*(32.8 s)+ 0.5*(3.20 m/s2)*(32.8 s)2
d = 1720 m
2.
d = vi*t + 0.5*a*t2 110 m = (0 m/s)*(5.21 s)+ 0.5*(a)*(5.21 s)2
110 m = (13.57 s2)*a
a = (110 m)/(13.57 s2)
a = 8.10 m/ s2
3.
d = vi*t + 0.5*a*t2 d = (0 m/s)*(2.6 s)+ 0.5*(-9.8 m/s2)*(2.6 s)2
d = -33 m (- indicates direction)
vf = vi + a*t
vf = 0 + (-9.8 m/s2)*(2.6 s)
vf = -25.5 m/s (- indicates direction)
4.
a = (Delta v)/t a = (46.1 m/s - 18.5 m/s)/(2.47 s)
a = 11.2 m/s2
d = vi*t + 0.5*a*t2
d = (18.5 m/s)*(2.47 s)+ 0.5*(11.2 m/s2)*(2.47 s)2
d = 45.7 m + 34.1 m
d = 79.8 m
(Note: the d can also be calculated using the equation vf2 = vi2 + 2*a*d)
5.
d = vi*t + 0.5*a*t2 -1.40 m = (0 m/s)*(t)+ 0.5*(-1.67 m/s2)*(t)2
-1.40 m = 0+ (-0.835 m/s2)*(t)2
(-1.40 m)/(-0.835 m/s2) = t2
1.68 s2 = t2
t = 1.29 s
6.
a = (Delta v)/t a = (444 m/s - 0 m/s)/(1.80 s)
a = 247 m/s2
d = vi*t + 0.5*a*t2
d = (0 m/s)*(1.80 s)+ 0.5*(247 m/s2)*(1.80 s)2
d = 0 m + 400 m
d = 400 m
(Note: the d can also be calculated using the equation vf2 = vi2 + 2*a*d)
