To calculate the horizontal distance traveled by the ball, we first calculate the total time it takes to reach the ground as follows:
t = √[2y/g] = <span>√[2(0.55) / 9.81]
t = 0.33 s
The horizontal distance would be
</span><span>X = Vx*t = 1.2*√[2*.55/9.8] = 0.4 m
</span>
Hope this helps.
For the same generic reason that table salt doesn't taste or behave
like the corrosive sodium or the poisonous chlorine that it's made of.
The physical and chemical properties of compounds in general are
very different from the characteristics of any of their constituent
elements in the pure elemental state.
-- Water doesn't act anything like Hydrogen or Oxygen.
-- A candle doesn't act anything like Carbon or Hydrogen.
-- Dry ice doesn't act anything like Carbon or Oxygen.
-- DNA doesn't act anything like Hydrogen, Oxygen, Nitrogen,
Carbon or Phosphorus. (We are lucky.)
Answer:
v = 4.264 m/s
Explanation:
It is given that,
Mass of the ball, m = 0.15 kg
Spring constant of the spring, k = 150 N/m
The spring is compressed by a distance, x = 0.05 m
The pellet's initial velocity is at an angle θ (θ < 90) above the horizontal.
Let v is the final speed of the projectile when it is at a distance h = 0.800 m below its initial height. It can be calculated using the conservation of energy as :
v = 4.264 m/s
So, the final speed of the projectile is 4.264 m/s. Hence, this is the required solution.
Power = (current) x (voltage) .

first well then you align the decimals together and then go down like you normally do
