Answer:
a) ω=n
b) V = R*n
c) a = 0
d)
Explanation:
Angular velocity is given by the derivative of θ:
ω = n
Linear Velocity will be:
V = ω*R = n*R
Tangential acceleration will be the derivative of the linear velocity. Since velovity is constant:
a = 0
Radial acceleration is given by:
Answer:
Thus, the average velocity is 9.73 m/s.
Explanation:
The velocity is given by the rate of change of position.
initial position, A = (9.2, 3.1) m
final position, B = (72.2, 77.2) m
time, t = 10 s
The velocity is given by
