Answer:
The centripetal force acting on the car is proportional to the mass of the car.
Explanation:
Let,
The mass of the car be 'm'
The velocity of the car moving in the curved path be 'v'
The radius of the curved path be 'r'
According to physics, a body moving ion circular path experience a force directed along the radius of the path. This force is called centripetal force.
The formula for centripetal force is,
<em>F = mv²/r</em>
Where,
a = v²/r
So, if the mass of the car changes, the centripetal force also changes proportionally according to the above equation.
It takes about a really long time
<u>T</u><u>he area w</u><u>h</u><u>ich touches the sand floor of 4 feet of the bull is less than the man.</u>
because the area of surface of contact is more in bull than in man. More is the area of contact, leads is the force or pressure affected.
For this case we have the following equation:
-16t + 8t + 8 = 0
The first thing we must do is rewrite the equation correctly.
We have then:
-16t ^ 2 + 8t + 8 = 0
Solving the polynomial we have:
t1 = -1/2
t2 = 1
We discard the negative root because we want to find the time.
Answer:
it takes for the object to reach the ground about:
t = 1 second
