Answer:
0.78 m
Explanation:
By the conservation of energy, the energy that they gain from potential energy, must be equal to the kinetic energy. So, for Adolf:
Ep = Ek
ma*g*ha = ma*va²/2
Where ma is the mass of Adolf, g is the gravity acceleration (10 m/s²), ha is the height that he reached, and va is the velocity. So:
100*10*0.51 = 100*va²/2
50va² = 510
va² = 10.2
va = √10.2
va = 3.20 m/s
Before the push, both of them are in rest, so the momentum must be 0. The system is conservative, so the momentum after the push must be equal to the momentum before the push:
ma*va + me*ve = 0, where me and ve are the mass and velocity of Ed. So:
100*3.20 + 81ve = 0
81ve = 320
ve = 3.95 m/s
By the conservation of energy for Ed:
me*g*he = me*ve²/2
81*10*he = 81*(3.95)²/2
810he = 631.90
he = 0.78 m
Answer:
<h3> B. 4 m/s</h3>
Explanation:
The formula for Speed is distance per time.
<h3>Therefore Speed = Distance / Time</h3>
<u>Data</u>
D = 40 m
T = 10 sec
S = ?
<h3> Speed = 40m /10sec</h3>
To find the speed , divide the distance by the time.
Note : the unit for Speed is meter /second
<h3> Speed = 4 m/s</h3>
Therefore the speed of the wave, the surfer is riding on is 4 m/s.
The firearm is unloaded.
The ramrod establishes whether the firearm is loaded or unloaded. It thrusts the bullet down the barrel. It is marked by wrapping some tape around it ( at the muzzle end ). This is to effectively signal if the muzzleloader is empty or loaded.
