Answer:
The value is
Explanation:
From the question we are told that
The velocity of the each of the three cars is
The velocity of the fourth car is
The initial velocity of the fifth car
Generally from the law of momentum conservation we have that
Given that the cars are identical then their mass will be the same
i.e

Ryan applied a force of 10N and moved a book 30 cm in the direction of the force. How much was the work done by Ryan?
<h2><u>Answer:</u><u>-</u></h2><h3>Given,</h3>=> Force applied by Ryan = 10N
=> Distance covered by the book after applying force = 30 cm
<h3>And,</h3>30 cm = 0.3 m (distance)
<h3>So,</h3>=> Work done = Force × Distance
=> 10 × 0.3
=> 3 Joules
