for a solid cylinder:
for a hollow cylinder:
I will look at the case of a hollow cylinder:
That is as far as i get.
Answer:
The velocity of the block is 231650.8 ft/s
Explanation:
Knowing
W = 10 lb
v0 = u = 4 ft/s
F = 8 lb
ms = 0.2
Applying the newton second law
ΣFy = 0
N - W = 0 --> N = W = 10 lb
ΣFx = m
F - ms N = ma
- 0.2(10) =
a =
Using Kinematics
a = dv/dt
= =
v - 4 = 3.22
when t = 30
v = 231650.8 ft/s
