Answer:
α = 1.32 rad/s²
Explanation:
given,
diameter of the bicycle = 0.8 m
radius of the bicycle = 0.4 m
initial speed of the bicyclist,u = 0 m/s
final speed of the bicyclist,v = 22 Km/h = 22 x 0.278
= 6.12 m/s
time,t = 11.6 s
acceleration =
=
=0.53 m/s²
we know,
a = α r


α = 1.32 rad/s²
the angular acceleration of the wheels is equal to α = 1.32 rad/s²
Answer:True
Explanation:
True
Even though it is easier to concentrate on the urgent and sometimes specific issues of a given project, project managers and all other personnel must bear in mind the influence of any project on the wants and needs of the entire system or organization.
A Project manager must perform following duties
- Planning Project resources
- Lead the team
- Time management
- Budget
- Documentation
After the second car starts out,
D = 30 + 110 H
360 = 30 + 110 H
330 = 110 H
H = 330/110
H = 3 hours after the second car leaves.
That's 3.5 hours after the first car leaves.
