Answer:
The speed of the golf ball just after the impact is 73.04 m/s.
Explanation:
Given that,
The mass of golf club, m₁ = 183 g = 0.183 kg
The mass of golf ball, m₂ = 46.6 g = 0.0466 kg
The initial speed of golf club, u₁ = 58.6 m/s
The initial speed of a golf ball, u₂ = 0
The final speeds of club, v₁ = 40 m/s
We need to find the speed of the golf ball just after impact. Using the conservation of momentum to find it.
So, the speed of the golf ball just after the impact is 73.04 m/s.
Answer:
Speed is the rate at which an object's position changes, measured in meters per second. The equation for speed is simple: distance divided by time
Explanation:
IF that were true, then you could take some of the work from the output,
put it back into the input to keep the machine running, and use the rest
to run the lights and the hot water heater in your house. That way, you'd
never need to buy energy from the electric company.
You NEVER get more work out of a machine than you put into it.
Never never never.
(Unless there's a battery or a tiny gasoline engine or a hamster
on a treadmill inside.)
The weight of anything is determined on how much gravity is pulling on the object. For example a balloon full of helium floats away but iron or concrete would fall to the ground. hope this helps :)
One double bond consists 4 electrons, so 2 double bonds means 8 electrons
