Calculate the magnitude of the gravitational force exerted on a 4.20 kg baby by a 100 kg father 0.200 m away at birth (he is assisting, so he is close to the child). (b) calculate the magnitude of the force on the baby due to jupiter if it is at its closest distance to earth, some 6.29×1011 m.

(a). The magnitude of the gravitational force is

(b). The magnitude of the gravitational force is

Explanation:

Given that,

Mass of baby = 4.20 kg

Mass of father = 100 kg

Distance = 0.200 m

We need to calculate the gravitational force

Using gravitational formula

Put the value in to the formula

(b). We need to calculate the gravitational force

Using gravitational formula

Put the value in to the formula

Hence, (a). The magnitude of the gravitational force is

(b). The magnitude of the gravitational force is

prolly a beacuse the momentuem the car has increases while going down hill

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
