Answer:

$V=\dfrac{3}{2}\ m/s$

Explanation:

Two identical bodies are sliding toward each other on a frictionless surface.

Initial speed of body 1, m₁ = 1 m/s

Initial speed of body 2, m₂ = 2 m/s

They collide and stick.

We need to find the speed of the combined mass. Let V is the speed of the combined mass.

Using the conservation of momentum.

$m_1u_1+m_2u_2=V(m_1+m_2)$

We have, m₁ = m₂ = m

$m\times 1+m\times 2=(m+m)V\\\\m+2m=2m\times V\\\\3m=2mV\\\\V=\dfrac{3}{2}\ m/s$

So, the speed of the combined mass is $\dfrac{3}{2}\ m/s$ .

A stone of mass 0.2 kg falls with an acceleration of 10.0 m/s. How big is the force that causes this acceleration?

Kobotan [32]

Answer:

$\boxed {\boxed {\sf 2 \ Newtons}}$

Explanation:

According to Newton's Second Law of Motion, force is the product of mass and acceleration.

$F= m \times a$

The mass of the stone is 0.2 kilograms and the acceleration is 10.0 meters per square second.

m= 0.2 kg
a= 10.0 m/s²

Substitute the values into the formula.

$F= 0.2 \ kg * 10.0 \ m/s^2$

Multiply.

$F=2 \ kg*m/s^2$

Convert the units.

1 kilogram meter per square second (kg*m/s²) is equal to 1 Newton (N)
Our answer of 2 kg*m/s² is equal to 2 N

$F= 2 \ N$

The force is <u>2 Newtons.</u>
