My guess for this one would be; 400 N
My reasoning would be; it starts at 0 on both X and Y, if you need to get to 1.00 meters thats 4/4. 1/4 of 1.00 is .25, and on .25 its on 100 so multiply it by 4 to make 1.00 and you get 400 N
Answer:
A) How much work does the Pepsi do on the bullet = 0.0625J
B) At what velocity does the Pepsi hit the floor = 7.67m/s
Explanation:
- Given mass of bullet = 5g
- initial velocity = 500 m/sec
From work done = Force X Distance
Workdone ; m(v - u )/t
A) The work done by the Pepsi is equal to the change in kinetic energy while in the Pepsi:
- but The work done by the container wall on the bullet is equal to the change in kinetic energy on either side of the wall: W = change in kinetic energy = 1/2 mv²
= 1/2 X 0.005 x 500² - 1/2 X 0.055 x 5²
= 624.94J
- Therefore ; The work done by the Pepsi is equal to the change in kinetic energy while in the Pepsi = W = change in KE = 0.0625 - 0 = 0.0625J
B) At what velocity does the Pepsi hit the floor?
- From conservation of energy principle; PE = KE
Answer: The answer is right here and it is corrct
:)
Explanation: I think you can unblocked it but Hope this help :)
When acid reacts with water, the hydroxide ion is formed I think it is true.
If a motorcycle accelerates from 10 m/s
to 15 m/s in 5 seconds, the average acceleration of the bike is 3 m/s/s. This only
means that the motorcycle’<span>s velocity will increase 3 m/s every second. You need to divide 15 m/s which is the
difference of 10 and 25 to 5 seconds.</span>
