Explanation:
USANDO LA SEGUNDA LEY DE NEWTON:
<em>m</em> = 10.0 N/ = 10.0 kg
Okay so you have to find acceleration first. I used v=vo+at. Plug in the numbers and you get -11.9m/s^2 as your constant acceleration. Then plug acceleration into d=vi(t)+1/2(a)t^2
d=(40m/s)(3.34s)+1/2(-11.9m/s^2)(3.34s)^2
d=68.6m
<u>Answer</u>
Fossils are remains from animals and plants. They are embedded in rock and preserved in petrified form.
In a fossil fuels power plant carbon fuels such as oil, coal and gas are burnt to generate steam that are used to turn large turbines that generate electricity.
These turbines turn magnetic fields inside conductor inducing a large current in them.
Fossils fuels are much reliable as they can be used for a long period of time.
Answer:
Explanation:
As we know that when runner is moving on straight track then the net force on his feet is given as
while when runner is moving on circular track then we have
now percentage change is given as
Total Mechanical Energy = KE + PE
KE = (1/2)mv²
= (1/2)*8*20² = 1600 J
PE = mgh g ≈ 10 m/s²
= 8 * 10 * 85 = 6800J
Total Mechanical = 1600 + 6800 = 8400 J.
