Answer:
see below
Explanation:
acceleration = Δv /Δt
for this situation 60 / 10 = 6 m/s^2
B) vf = vo + at
vf = 0 + 6(3) =<u> 18 m/s after 3 seconds </u>
<u />
C) vf = at
60 = 6 ( t) t = 10 seconds ( actually, this was given)
d = 1/2 a t^2
= 1/2 (6) (10)^2 = <u>300 m </u>
<u />
It's a negative value because the negative sign on the spring's force means the force exerted opposes the spring's displacement
Answer:
The object with the greater mass will have the greater momentum
Explanation:
The momentum of an object with mass <em>m</em>, moving with velocity <em>, </em>is given by the formula
M = <em>mv</em>
<em />
Since both objects have the same velocity <em>v, </em>it is clear that the object with the bigger mass will have the greater momentum
- P is power
- R is resistance
Hence
- Therefore if power is low then resistance will be high.
The first bulb has less power hence it has greater filament resistance.
