Answer:
the direction of the friction force on the car is in the same direction to the VELOCITY of the car.
Explanation:
When the brakes are applied on a moving car then the speed of the car reduces slowly. The slowing of speed and the stopping of car takes a certain time which is proportional to the force applied by the brakes.
The brakes when applied to the moving part on the axle of the vehicle be it either drum or the disc offers the resistance to the rotation of the wheels in the form of friction.
As we know that friction always acts in a direction opposite to the relative motion between the two surfaces. So does here in this case the friction of brakes acts in a direction tangentially opposite to the rotation at the point of application of the brakes.
Similarly, the friction between the tyres and the road acts in a direction tangentially opposite to the direction of the relative motion between the surfaces i.e. the tyres move backwards relative to the road surface and hence the friction acts in the forward direction and is in the same direction as the motion of the car.
a) Speed of the Moon: 1025 m/s
The speed of the moon is equal to the ratio between the circumference of its orbit and the orbital period:
where
is the radius of the orbit of the Moon
is the orbital period
Substituting into the formula, we find
b) Centripetal force:
The centripetal force acting on the Moon is given by:
where
is the mass of the Moon
is its orbital speed
is the radius of the orbit
Substituting into the formula, we find
c) Gravitational force
The only relevant force that acts on the Moon, and that keeps the Moon in circular motion around the Earth, is the gravitational force exerted by the Earth on the Moon. In fact, this force "pulls" the Moon towards the Earth, so towards the centre of the orbit of the Moon, therefore it acts as source of centripetal force for the Moon.
Answer:
We have the output force (3000) and the mechanical advantage is 15, the formula is Ma = F(o) / F(i), so 15 = 3000 / x, so x = 200 newtons!
