A 1000 kg car experiences a net force of 9500 N while slowing down from 30 m/s to 16 m/s. How far does it travel while slowing d
rjkz [21]

Answer:

33.89 m

Explanation:

We must first obtain the acceleration of the car from;

F=ma

Where

F= force= 9500 N

m= mass of the car= 1000kg

a= acceleration

a= F/m= 9500/1000

a= 9.5 m/s^2

From;

V^2=u^2 + 2as

Where;

V= final velocity

u= initial velocity

s= distance covered

a= acceleration

s= v^2 -u^2/2a

s= (30)^2 -(16)^2/2×9.5

s= 900 - 256/19

s= 644/19

s= 33.89 m

Object A attracts object B with a gravitational force of 10 Newton’s from a given distance. If the distance between the two obje
madam [21]

If the distance between two objects is doubled, then the gravitational forces between them become (1/2)² = 1/4 of the original gravitational forces.

If the magnitude of those forces was 10 Newtons before the move then they're 2.5 Newtons after it.

I changed the wording of the discussion to plural, because the wording in the question is misleading.  It shouldn't say "Object A attracts Object B" and then let it go at that.  Gravitational forces ALWAYS occur in equal pairs.  If Object B feels a pull of 10 Newtons toward Object A, then Object A feels a pull of 10 Newtons toward Object B.  

The masses don't even matter.  Gravity is always there equally in both directions.  Your weight on Earth is equal to the Earth's weight on you !

Gibbons, small Asian apes, move by brachiation, swinging below a handhold to move forward to thenext handhold. A 9.3kggibbon has
Mumz [18]

Upward force provided by the branch is 260 N

<u>Explanation:</u>

Given -

Mass of Gibbon, m = 9.3 kg

Length of the branch, r = 0.6 m

Speed of the movement, v = 3.3 m/s

Upward force, T = ?

The tension force in the rod must be greater than the weight at the bottom of the swing in order to provide an upward centripetal acceleration.

Therefore,

F net = T - mg

F net = ma = mv²/r

Thus,

T = mv²/r + mg

T = m ( v²/r + g)

T = 9.3 [ ( 3.3)² / 0.6 + 9.8]

T = 259.9 N ≈ 260 N

Therefore, upward force provided by the branch is 260 N
