Answer:
Area = 20 m²
Explanation:
Given the following data;
Force = 2500 N
Pressure = 125 Pa
To find the area on which it rest;
Mathematically, pressure is given by the formula;
Making area the subject of formula, we have;
Substituting into the formula, we have;
Area = 20 m²
Answer:
a)
b)
Explanation:
The net force on the car must produce the centripetal acceleration necessary to make this circle, which is . At the top of the circle, the normal force and the weight point downwards (like the centripetal force should), while at the bottom the normal force points upwards (like the centripetal force should) and the weight downwards, so we have (taking the upwards direction as positive):
Which means:
The limit for falling off would be , so the minimum speed would be:
