Answer:
d = 10.2 m
Explanation:
When the car travels up the inclined plane, its kinetic energy will be used to do the work in climbing up. So according to the law of conservation of energy, we can write that:
![Kinetic\ Energy\ of\ the \ Car = Work\ Done\ while\ moving\ up\ the\ plane\\\frac{1}{2}mv^{2} = Fd](https://tex.z-dn.net/?f=Kinetic%5C%20Energy%5C%20of%5C%20the%20%5C%20Car%20%3D%20Work%5C%20Done%5C%20while%5C%20moving%5C%20up%5C%20the%5C%20plane%5C%5C%5Cfrac%7B1%7D%7B2%7Dmv%5E%7B2%7D%20%3D%20Fd)
where,
m = mass of car
v = speed of car at the start of plane = (36 km/h)(1000 m/1 km)(1 h/3600 s)
v = 10 m/s
F = force on the car in direction of inclination = W Sin θ
W = weight of car = mg
θ = Angle of inclinition = 30°
d = distance covered up the ramp = ?
Therefore,
![\frac{1}{2}mv^{2} = mgdSin\theta\\\frac{1}{2}v^{2} = gdSin\theta\\\frac{1}{2}(10\ m/s)^{2} = d(9.81\ m/s^{2}) Sin\ 30^{0}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7Dmv%5E%7B2%7D%20%3D%20mgdSin%5Ctheta%5C%5C%5Cfrac%7B1%7D%7B2%7Dv%5E%7B2%7D%20%3D%20gdSin%5Ctheta%5C%5C%5Cfrac%7B1%7D%7B2%7D%2810%5C%20m%2Fs%29%5E%7B2%7D%20%3D%20d%289.81%5C%20m%2Fs%5E%7B2%7D%29%20Sin%5C%2030%5E%7B0%7D)
<u>d = 10.2 m</u>
Answer:
to check for errors.
Explanation:
since some of the components of the scale are metallic, they are prone to rusting which would cause error in reading of the scale so there is organized checking if the scale to correct that.
hope it helps .
Answer:
frictonal force due to the surface of irregularities
Weight on the Moon = 291 N.
W = g · m, where m stays for the mass and on the Moon g = 1.67 m/s²
291 N = 1.67 m/s² · m
m = 291 kg m / s² : 1.67 m/s²
m = 174.25 kg
Weight on Earth = 9.81 m/s² · 174.25 kg = 1,709.4 N
Answer:
The weight of an astronaut on Earth is 1,709.4 N.
