Answer:
x=?
dt=?
vi=23m/s
vf=0m/s (it stops)
d=0.25m/s^2
time =
vf=vi+d: 0=23m/s+(0.25m/s^2)t
t=92s
displacement=
vf^2=vi^2+2a(dx)
23^2=0^2+2(0.25m/s^2)x =-1058m
Explanation:
you can find time from vf = vi + a(Dt): 0 = 23 m/s + (0.25 m/s/s)t so t = 92 s and you can find the displacement from vf2 = vi2 + 2a(Dx) and find the answer in one step: 232 = 02 + 2(0.25 m/s/s)x so x = -1058 m
A white ring buoy appears<u> blue</u> because the blue plastic <u>absorbs</u> all colors of light except blue. Only the blue light <u>reflected from</u> the ring buoy passes through the blue plastic.
<u><em>Answer:</em></u>
Momentum of the skier is 350 Kg.m/sec
<u><em>Explanation:</em></u>
<u>Momentum of a body can be calculated using the following rule:</u>
P = m * v
<u>where:</u>
P is the momentum of the body
m is the mass of the body given as 70 Kg
v is the velocity of the body given as 5 m/sec
<u>Substitute with the givens in the above rule to get the momentum of the skier as follows:</u>
P = m * v
P = 70 * 5
P = 350 Kg.m/sec
