Answer:
The position function is 
.
Explanation:
Given that,
Acceleration 
Initial velocity 
Initial displacement 
We know that,
The acceleration is the rate of change of velocity of the particle.
The velocity is the rate of change of position of the particle
We need to calculate the the position
The acceleration is
On integration both side
At t = 0
Now, On integration again both side
At t = 0
Hence, The position function is .

Answer:
a) t = 0.74s
b) D = 4.76m
c) Vf = 5.35m/s
Explanation:
The ball starts rolling when Vf = ωf*R.
We know that:
Vf = Vo - a*t
ωf = ωo + α*t
With a sum of forces on the ball:
With a sum of torque on the ball:
Replacing both accelerations:
t=0.74s
The distance will be:
Final velocity:
Vf=5.35m/s
In space we feel weightlessness because the earths gravity has less effect on us.The Earths gravitational attraction at those altitudes is only about 11% less than it is at the Earths surface. If you had a ladder that could reach as high as the the shuttles orbit, your weight would be 11% less at the top.
