<span>A motor produces less mechanical energy than the energy it uses because the motor looses some energy to heat.</span>
When a police officer is trying to decide if a driver is speeding, what is his point of reference. The speed limit
The new force would be 1.6 N.
Since the charges multiply as variables (q1)x(q2), then it would simply be double (q1)x(q2), or 1.6.
Answer:

Explanation:
We need to apply conservation of momentum and energy to solve this problem.
<u>Conservation of momentum</u>

(1)
- m(c) is the mass of stick clay
- m(w) is the mass of the wooden block
- v(ic) is the initial velocity of clay
- V is the final velocity of the system clay plus wood.
<u>Conservation of total energy</u>
The change in kinetic energy is equal to the change in internal energy, in our case it would be the energy loss due to the friction force. Let's recall the definition of work, it is the dot product between force and displacement, Therefore:



We can find V from this equation:

Now, let's put V into the equation (1) and find v(ic)

I hope it helps you!
