Answer:
66,7 seconds
Explanation:
the formula for height/distance is : S=v.t
Answer:
0.43622 seconds
0.9158 foot
-4.43 ffot/sec
Explanation:
we first find the period of oscillation
= 2π√w/gk
= 2π√4000/32x2600
= 2π√0.00481
= 2π0.0694
= 0.43622
b. we find the angular velocity
2π/T
= 2π/0.43622
= 14.41 rad/sec
we find displacement
rom the calculation in the attachment
Ф = -144.1
initial condition
1*cos(-144.1 rad)
= 0.9158 foot
initial velocity of the car
= (-1)(14.41)sin(ω(0)-144.1)
= -4.44 foot/sec
Answer:
a. decrease by a factor of 3.
Explanation:
The intensity of light is inversely proportional to the square of distance.
I ∝1/d^2
or
I= k/d^2
where k is a constant
so, if d becomes 2d , I will be come I/4
Therefore, intensity will a. decrease by a factor of 3.
