Inertia, property of a body by virtue of which it opposes any agency that attempts to put it in motion or, if it is moving, to change the magnitude or direction of its velocity. Inertia is a passive property and does not enable a body to do anything except oppose such active agents as forces and torques.

Which of the following statements is an example of absolute time?
Nataly_w [17]
I think the answer is : Bobby exactly three years old today

to put it simply, absolute time can be perceived without depended to other object as comparison.

for example Evan is older than james is not an absolute time, because this conditions depend on the age comparison between the two subject

Can someone pls answer number 8 for me pls
fomenos

Answer:

1.33 m

Explanation:

Tom weighs 600 N and is 2 meters from the pivot.  So his moment is:

τ = Fr

τ = (600 N) (2 m)

τ = 1200 Nm

To balance the see-saw, Jeremy must create an equal and opposite moment.

τ = Fr

1200 Nm = (900 N) r

r = 1.33 m

So Jeremy must sit 1.33 m from the pivot on the other side.

Part C: Quantitative Problems when vf is not 0
Alina [70]

Answer:

(a)

\triangle v=-8\ m/s\\\triangle mv=-56\ kg.m/s

(b)

1120 N

Explanation:

Change in velocity, \triangle v is given by subtracting the initial velocity from the final velocity and expressed as \triangle v= v_f -v_i

Where v represent the velocity and subscripts f and i represent final and initial respectively. Since the ball finally comes to rest, its final velocity is zero. Substituting 0 for final velocity and the given figure of 8 m/s for initial velocity then the change in velocity is given by

\triangle v=0-8=-8\ m/s

To find m\triangle v then we substitute 7 kg for m and -8 m/s for \triangle v therefore \triangle\ v=7 Kg\times -8 m/s=-56\ Kg.m/s

(b)

The impact force, F is given as the product of mass and acceleration. Here, acceleration is given by dividing the change in velocity by time ie

a=\frac {\triangle v}{t}=\frac { v_f -v_i}{t}

Substituting t with 0.05 s then a=\frac {\triangle v}{t}=\frac { v_f -v_i}{t}=\frac {-8}{0.05}=-160 m/s^{2}

Since F=ma then substituting m with 7 Kg we get that F=7*-160=-1120 N

Therefore, the impact force is equivalent to 1120 N
