6m at 0.9 radian means 6m at
Since positive angles are counter clockwise
6m at can be written as 6*cos
i+6*sin
j = 3.73i+4.70j
5m at can be written as 5*cos
i+5*sin
j = 1.294i-4.83j
4m at 1.2 radian means 4m at
4m at can be written as 4*cos
i+4*sin
j = 1.45i+3.73j
6m at can be written as 6*cos
i+6*sin
j = -5.20i-3j
a) So sum of the vector = 1.274i+0.6j
b) Magnitude =
c) Angle,
Answer:
230
Explanation:
= Rotational speed = 3600 rad/s
I = Moment of inertia = 6 kgm²
m = Mass of flywheel = 1500 kg
v = Velocity = 15 m/s
The kinetic energy of flywheel is given by
Energy used in one acceleration
Number of accelerations would be given by
So the number of complete accelerations is 230
Okay, haven't done physics in years, let's see if I remember this.
So Coulomb's Law states that
so if we double the charge on 
and double the distance to 
we plug these into the equation to find
<span>
</span>
So we see the new force is exactly 1/2 of the old force so your answer should be
if I can remember my physics correctly.
