Question

M1=60кг V1=3 m/с m2=45кг V2=?​

Answer 1

Ответ:

m1=60кг

V1= 3 m/c

m2=45 кг

V2=?

m1+m2 : v1 (оформишь как надо по правилам v1 под чертой)

60+45 /3= 35

Ответ V2 = 35 m/c

Answer 2

To solve this problem, you can use the principle of conservation of momentum. The total momentum before a collision is equal to the total momentum after the collision, assuming no external forces are involved. Mathematically, this can be expressed as:

$M1 * V1 + M2 * V2 = (M1 + M2) * Vf$

Where:

• $M1$ and $M2$ are the masses of objects 1 and 2 respectively,
• $V1$ and $V2$ are their initial velocities,
• $Vf$ is the final velocity after the collision.

Plugging in the given values:

• $M1 = 60 \, \text{kg}$,
• $V1 = 3 \, \text{m/s}$,
• $M2 = 45 \, \text{kg}$,
• $V2$ is what we're trying to find.

The total mass after the collision $M1 + M2 = 60 \, \text{kg} + 45 \, \text{kg} = 105 \, \text{kg}$.

Now we can solve for $V2$:

$M1 * V1 + M2 * V2 = (M1 + M2) * Vf$

$60 \, \text{kg} * 3 \, \text{m/s} + 45 \, \text{kg} * V2 = 105 \, \text{kg} * Vf$

$180 \, \text{kg m/s} + 45 \, \text{kg} * V2 = 105 \, \text{kg} * Vf$

Now, rearrange the equation to solve for $V2$:

$45 \, \text{kg} * V2 = 105 \, \text{kg} * Vf - 180 \, \text{kg m/s}$

$V2 = \frac{105 \, \text{kg} * Vf - 180 \, \text{kg m/s}}{45 \, \text{kg}}$

Since no information is given about whether the collision is elastic or inelastic, we can't directly determine $Vf$ without additional information.

If the collision is elastic, you'll need to use additional equations involving coefficients of restitution. If the collision is inelastic, the objects will stick together after the collision, and $Vf$ will be the final velocity of the combined mass.
