Explanation / Answer

1)
Initial Velocity, u = 0
Acceleration, a = - 6.2 * cos(29) i^ + 6.2*sin(29) j^

Acceleration in southerly direction, =  6.2*sin(29) m/s^2

t = 11s
Distance travelled,
S = u*t + 1/2at^2
S = 0 +1/2 * 6.2*sin(29) * 11^2
S = 181.85 m
Distance travelled in southerly direction, S = 181.85 m

2)
r = 185/2 = 92.5 m
g = ²r
= (g/r)
= (9.8/92.5)
= 0.325 rad/s
Anhular velocity, = 0.325 rad/s
