Answer:
The maximum speed of the car is 31.46 m/s.
Explanation:
Given that,
Radius = 101 m
We need to calculate the maximum speed that the car can go over the hill without leaving the road
Using relation of normal force and centripetal force
Where, m = mass of car
Put the value into the formula
Hence, The maximum speed of the car is 31.46 m/s.
Explanation:
There exist a force of gravity between two masses. It is given by :
...........(1)
Where
G is the universal gravitational constant
m₁ and m₂ are masses
r is the distance between them
From equation (1) it is clear that the force of gravity between two masses is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
So, the gravitational force between two objects is <em><u>directly proportional</u></em> to the product of the masses of the objects
