The time elapsed since you stopped the stopwatch is 0.41 s.
<em>Your question is not complete, it seems to be missing the following information;</em>
"The velocity of the ant is 2 m/s"
The given parameters;
- velocity of the ant, v = 2 m/s
- change in position of the ant, Δx = 0.81 m
- time when the ant was noticed, = t₂
Velocity is defined as the change in displacement per change in time of motion of an object.

The time elapsed since you stopped the stopwatch is calculated as;

Thus, the time elapsed since you stopped the stopwatch is 0.41 s.

Inertia is the resistance of any physical object to any change in its velocity. This includes changes to the object's speed, or direction of motion.
True. Since Inertia states this law, we are bound to believe greater mass = greater resistance in change of motion
Answer:
The angular momentum of the wheel is
.
Explanation:
It is given that,
Mass of the wheel, m = 2.73 kg
Radius of the wheel, r = 31 cm = 0.31 m
Angular speed of the wheel, 
We need to find its angular momentum. It is given by :

I is the moment of inertia of the wheel, 



So, the angular momentum of the wheel is
. Hence, this is the required solution.
