Answer:
Speed of both blocks after collision is 2 m/s
Explanation:
It is given that,
Mass of both blocks, m₁ = m₂ = 1 kg
Velocity of first block, u₁ = 3 m/s
Velocity of other block, u₂ = 1 m/s
Since, both blocks stick after collision. So, it is a case of inelastic collision. The momentum remains conserved while the kinetic energy energy gets reduced after the collision. Let v is the common velocity of both blocks. Using the conservation of momentum as :
![m_1u_1+m_2u_2=(m_1+m_2)v](https://tex.z-dn.net/?f=m_1u_1%2Bm_2u_2%3D%28m_1%2Bm_2%29v)
![v=\dfrac{m_1u_1+m_2u_2}{(m_1+m_2)}](https://tex.z-dn.net/?f=v%3D%5Cdfrac%7Bm_1u_1%2Bm_2u_2%7D%7B%28m_1%2Bm_2%29%7D)
![v=\dfrac{1\ kg\times 3\ m/s+1\ kg\times 1\ m/s}{2\ kg}](https://tex.z-dn.net/?f=v%3D%5Cdfrac%7B1%5C%20kg%5Ctimes%203%5C%20m%2Fs%2B1%5C%20kg%5Ctimes%201%5C%20m%2Fs%7D%7B2%5C%20kg%7D)
v = 2 m/s
Hence, their speed after collision is 2 m/s.

Answer:
P = 4.5 watts
Explanation:
Given that,
EMF of the circuit, E = 3 volt
The resistance of the resistors, R = 2 ohms
We need to find the power of this circuit. The relation between power, emf and resistance is given by the formula as follows :
![P=\dfrac{V^2}{R}](https://tex.z-dn.net/?f=P%3D%5Cdfrac%7BV%5E2%7D%7BR%7D)
Substitute all the values,
![P=\dfrac{3^2}{2}\\\\P=4.5\ W](https://tex.z-dn.net/?f=P%3D%5Cdfrac%7B3%5E2%7D%7B2%7D%5C%5C%5C%5CP%3D4.5%5C%20W)
So, the power of this circuit is equal to 4.5 watts.
