Answer:

Explanation:

mass of clay = m

velocity is u

By use of conservation of momentum

m x u - m x u = (m + m) x v

v = 0

So, they stick together and comes to rest.

The foot pedal on hydraulic brake system exerts a force of 45 lb on a piston with a diameter of 1.00 cm. The brake fluid in the
ElenaW [278]

Answer:

the correct answer is C,   281 lb

Explanation:

This is an exercise in fluid mechanics specifically on Pascal's principle, which states that the pressure in a fluid is equal to all points that are at the same depth

             P = \frac{F_{1} }{A_{1} } = \frac{F_{2} }{A_{2} }

If we use the subscript 1 for the piston diameter mentor (d = 1.00vm) which is r = 0.05 cm, the force is F1 = 45 lb

          F₂ = \frac{F_{1} }{A_{1} }  F₁

in area of ​​a circules

         A = π r²

we substitute

          F₂ = \frac{r_{2}^2 }{r_{1}^2}  F_{1}

let's calculate

           F2 = 2.50² / 1.00²  45

           F2 =281  lb

therefore the correct answer is C

A toy dart gun has a spring with k= 128 N/m. How much force does it take to pull the spring back 0.0500 m? (Unit = N)​
yKpoI14uk [10]

Answer:

F = 0.64 N

Explanation:

We are given;

Spring constant constant; k = 1.28 N/m

Distance; x = 0.5 m

From Hooke's law, we know that F = kx.

Thus;

F = 1.28 × 0.5

F = 0.64 N

Thus, force it takes to pull the spring back = 0.64 N
