Explanation:
We are given that
Mass of venus=
Radius=m
Mass of human=
We know that the gravitational force between two bodies
Where G=Gravitational constant=
Using the formula
The magnitude of the gravitational force exerted by Venus on the human=
The magnitude of the gravitational force exerted by Venus on the human=F=
At speeds over 30 mph, you should maintain a following distance of at least <u>three full seconds</u> behind the vehicle ahead of you.
As a general rule and common sense at a speed of 30 mph you can leave three full seconds so that you can achieve a prudent distance between the car you are driving and the car in front in order to be able to perform some kind of maneuver if an accident or unforeseen event occurs.
To count the full three seconds you can use the technique of counting the Mississippis as follows: Mississippi one, Mississippi two, Mississippi three.

As we know that friction force is always try to oppose the motion of an object. It means that it provide acceleration in the negative direction.
We know that
So the friction force on the box
Ff= m x a
Where m is the mass of the box.
