Answer:
simple machines such as ramps lessen the moment required to do work. if a triangle has a base of 5 and the height is 7, a ramp would make the hypotenuse of this triangle lessoning the total distance. using a²+b²=c² 25+49=c² 74≈8.6 and it is obvious that 8.6 is less than 12 in every unit. other simple machines such as pulleys make it lighter making it simply easier for an object to be lifted.
Explanation:
The gravitational force on the car is
(9.8 m/s^2) x (the car's mass in kg).
The unit is newtons.
200 N, that is if the force is balanced and the wall doesn't move
