Answer:
The sponge must go deep
Explanation:
If F = 6360 N, then it is required to find how deep can an object with this force hitting on a sponge get.
We know that, F = mgh
m is mass
g is acceleration due to gravity
So, the sponge must go deep.
A 2-kg toy car accelerates from 5 to 10 m/s in 2 seconds. Find the applied force.
<h2><u>Answer:</u></h2>Force applied is .
Force is defined as something which changes or tends to change the velocity of a body. And acceleration is defined as the rate of change of velocity of a body per time. Both of them are vector quantities.
The initial velocity of the body = 5 m/s.
The final velocity of the body = 10 m/s.
So the change in velocity = 10 - 5 m/s = 5m/s.
Time period = 2 seconds.
So acceleration ==
The force is defined as the product of mass and acceleration of the body.
Mass of body = 2 kg.
So, force applied = . =
.
Answer
given,
Mass of the solid sphere = 1800 Kg
radius of the sphere,R = 5 m
mass of the small sphere, m = 2.30 Kg
when the Point is outside the sphere the Force between them is equal to
when r>R
When Point is inside the Sphere
when r<R
where r is the distance where the point mass is placed form the center
Now Force calculation
a) r = 5.05 m
[/tex]
F = 1.082 x 10⁻⁸ N
b) r = 2.65 m
