Answer:
L = I α t
Explanation:
given,
rotational inertia = I
initial velocity = ω₀
magnitude of acceleration = α
angular momentum = L
time = t
angular acceleration
ω = α t..............(1)
angular momentum
L = I ω
putting value from equation (1)
L = I α t
The distance covered is 115 m
Explanation:
The motion of Ileana is a uniformly accelerated motion (constant acceleration), therefore we can use the following suvat equation:
where
s is the distance covered
u is the initiaal velocity
v is the final velocity
t is the time elapsed
In this problem, we have:
u = 4.20 m/s
v = 5.00 m/s
t = 25.0 s
Therefore, we can re-arrange the equation to find the distance covered:
