Let u = the vertical speed at launch, m/s
g = 9.8 m/s², acceleration due to gravity.
Part (a)
After 2.4 s, the vertical speed is 10 m/s.
Therefore
(10 m/s) = (v ft/s) - (9.8 m/s²)*(2.4 s)
v = 10 + 9.8*2.4 = 33.52 m/s
Answer: 33.52 m/s upward
Part (b)
After 5.1 s, the vertical speed is
(33.52 m/s) - (9.8 m/s²)*(5.1 s) = -16.46 m/s.
This means that the rock reached the maximum height and began falling downward.
Answer: 16.46 m/s downward
Answer:
When the machine indicates a lie, what is the probability that the suspect is really lying? If the machine does not indicate a lie, what is the probability that the suspect is really telling the truth?
My solution if the probability that a test subject is chosen at random from the 200 in fact lie = 80/(80+5)=0.94
Then when 15% of people arrested lie, the probability that the suspect is really lying is 0.15*0.94=0.141
Answer:
-5 m/s^2
Explanation:
10/2=5 and is is a stop so it is negitive
Answer:
41.4* 10^4 N.m^2/C
Explanation:
given:
E= 4.6 * 10^4 N/C
electric field is 4.6 * 10^4 N/C and square sheet is perpendicular to electric field so, area of vector is parallel to electric field
then electric flux = ∫ E*n dA
= ∫ 4.6 * 10^4 * 3*3
= 41.4* 10^4 N.m^2/C
