Answer:
6.13428 rev/s
Explanation:
= Final moment of inertia = 4.2 kgm²
I = Moment of inertia with fists close to chest = 5.7 kgm²
= Initial angular speed = 3 rev/s
= Final angular speed
r = Radius = 76 cm
m = Mass = 2.5 kg
Moment of inertia of the skater is given by
In this system the angular momentum is conserved
The rotational speed will be 6.13428 rev/s
Answer:
C
Explanation:
When we look at your cars speed at an exact moment for example 55 km/h this is instantaneous because there is no other given speeds at the time.
