Simple machines could be used to reduce effort or extend the ability of people to perform tasks beyond their normal capabilities.
Examples include pulley, lever, and incline plane
<span>internet tension = mass * acceleration internet tension = 23 – Friction tension = 14 * acceleration Friction tension = µ * 14 * 9.8 = µ * 137.2 23 – µ * 137.2 = 14 * acceleration Distance = undemanding speed * time undemanding speed = ½ * (preliminary speed + very final speed) Distance = ½ * (preliminary speed + very final speed) * time Distance = 8.a million m, preliminary speed = 0 m/s, very final speed = a million.8 m/s 8.a million = ½ * (0 + a million.8) * t Time = 8.a million ÷ 0.9 = 9 seconds Acceleration = (very final speed – preliminary speed) ÷ time Acceleration = (a million.8 – 0) ÷ 9 = 0.2 m/s^2 23 – µ * 137.2 = 14 * 0.2 resolve for µ</span>
<span>The force that opposes the movement of an object through
water is called drag. This is a type of frictional force. This force normally
depends on the density and the viscosity of the fluid in question. The liquid
which has more density and more viscosity or stickiness will produce a greater
amount of drag force on an object than a fluid that is less dense and less
viscous in nature. River water normally
has less drag than that of sea water. </span>
Answer: 125 m/s
Multiply 15 m/s by 5.0 minutes, because this will give you the product.
15 x 5.0 = 125.
Add the m/s sign to the 125. 125 m/s.
Answer = 125 m/s. Hope this helps!
