Two objects, X and Y, move toward one another and eventually collide. Object X has a mass of 2M and is moving at a speed of 2v0 to the right before the collision. Object Y has a mass of M and is moving at a speed of v0 to the left before the collision. Which of the following describes the magnitude of the forces F the objects exert on each other when they collide?a. The force exerted by X on Y is 4F to the right, and the force exerted by Y on X is F to the left. b. The force exerted by X on Y is 2F to the right, and the force exerted by Y on X is F to the left. c. The force exerted by X on Y is F to the right, and the force exerted by Yon X is F to the left. d. The force exerted by X on Y is F to the left, and the force exerted by Y on X is F to the right.

Respuesta :

The force exerted by object X on Y is 4F to the right and the force exerted by object Y on X is F to the left.

The given parameters;

  • mass of object X = 2M
  • initial velocity X = 2V₀
  • mass of object, Y = M
  • initial velocity of object Y = V₀

The force exerted by the object Y is calculated as follows;

[tex]F = \frac{mv}{t} \\\\[/tex]

where;

t is the time of impact

[tex]F_Y = \frac{MV_0}{t}[/tex]

The force exerted by the object X is calculated as follows;

[tex]F = \frac{mv}{t} \\\\[/tex]

[tex]F_X = \frac{2M \times 2V_0}{t} \\\\F_X = \frac{4MV_0}{t} \\\\F_X = 4(\frac{MV_0}{t} )[/tex]

[tex]F_X = 4(F_Y)[/tex]

Thus, we can conclude that the force exerted by object X on Y is 4F to the right and the force exerted by object Y on X is F to the left.

The force exerted by object X on Y is 4F to the right. And the force exerted by object Y on X is F to the left. Hence, option (a) is correct.

Given data:

The mass of object X is, 2M.

The initial velocity of X is, [tex]2v_{0}[/tex].

The mass of object Y is, M.

The initial velocity of Y is, [tex]v_{0}[/tex].

Applying the concept of impulse-momentum to obtain average force by object X as,

[tex]F=\dfrac{(2M)(2v_{0})}{t}\\F=\dfrac{4Mv_{0}}{t}[/tex]............................................................(1)

Here, t is the reaction time.

Similarly,  average force by the object Y is,

[tex]F'=\dfrac{Mv_{0}}{t}[/tex]...................................................................(2)

Taking ratio of equation (1) and (2) as,

[tex]\dfrac{F}{F'}=\dfrac{\dfrac{4Mv_{0}}{t}}{\dfrac{Mv_{0}}{t}}\\\dfrac{F}{F'}= 4\\F = 4F'[/tex]

Thus, we can conclude that the force exerted by object X on Y is 4F to the right. And the force exerted by object Y on X is F to the left. Hence, option (a) is correct.
