Newton's 2nd law of motion:
Force = (mass) x (acceleration)
For this man
on his bike: Force = (20 kg) x (5 m/s²)
= 100 newtons .
This is NOT the "force produced".
This is the force NEEDED in order to accelerate THAT man
and his bike at THAT rate. If you don't have something that
can apply THAT force, then you can't create this situation,
and he'll just have to carry on, in the same direction and at
the same speed, without turning, slowing down, or speeding up.
The answer is D) Cyclones. I am 100% sure on this one, so yeah. Hope this helps, and good luck. :D
N= energy efficiency pout means output and pin means input the reason this would show efficiency is because your output should be greater then your input and because depending on how small your number is after your division will tell you how efficient it is you want a big number.
Answer:
the larger-heavier would fall faster than lighter-smaller ball
Explanation:
Answer:
7 m/s
Explanation:
To solve this problem you must use the conservation of energy.
That math speak for, initial kinetic energy plus initial potential energy equals final kinetic energy plus final potential energy.
The initial PE (potential energy) is 0 because it hasn't been raised in the air yet. The final KE (kinetic energy) is 0 because it isn't moving. This gives the following:
K1=U2
Solve for v
Input known values and you get 7 m/s.
