Two blocks of mass 5 kg and 10 kg are placed in contact on a frictionless horizontal surface, as shown in the diagram below. A constant horizontal force, \(F\), is applied to the 5 kg block.
\(\text{Question 9}\)
Which one of the following statements is correct?
- The net force on each block is the same.
- The acceleration experienced by the 5 kg block is twice the acceleration experienced by the 10 kg block.
- The magnitude of the net force on the 5 kg block is half the magnitude of the net force on the 10 kg block.
- The magnitude of the net force on the 5 kg block is twice the magnitude of the net force on the 10 kg block.
\(\text{Question 10}\)
If the force \(F\) has a magnitude of 250 N, what is the work done by the force in moving the blocks in a straight line for a distance of 20 m?
- \(5 \text{ kJ}\)
- \(25 \text{ kJ}\)
- \(50 \text{ kJ}\)
- \(500 \text{ kJ}\)
