A block of mass m is compressed against a spring (spring constant kk) on a horizontal frictionless surface. The block is then re
Nimfa-mama [501]

Answer:

A) True, B) False, C) False  and  D) false

Explanation:

Let's solve the problem using the law of conservation of energy to know if the statements are true or false

Let's look for mechanical energy

Initial

     Emo = Ke = ½ k Dx2

Final

     Em1= ½ m v12

     Emo = Em1

     ½ k Δx2 = ½ m v₁²

    v₁² = k / m Δx²

    v₁ = √ k/m   Δx

Now let's calculate the speed when it falls

   Vfy² = Voy² - 2gy

   Vfy² = - 2gy

   Vf² = v₁² + vfy²

A) True     v₁ = A Δx

.B) False. As there is no rubbing the mechanical energy conserves

.C) False the velocity is proportional to the square root of the height

     v2y = v2 √2

. D) false promotional compression speed

amid [387]
Yhuihoifjhh <span>F = Gm1m2 / r^2 

if the masses are doubled then the force is increased by a factor of 4 


if the distance is doubled the force is decreased by a factor of 1/ 2^2 
the net result is no change in force</span>
