Question

A child runs 5 m/s down an airport walkway that is moving at 2 m/s in the same direction. What distance does the child cover in 10 seconds?

Answer 1

Answer #1

Effective speed = 5+2 = 7 m/s

Time t = 10 s

We know,

D = vt

= 7 * 10

= 70 m (answer)

Answer 2

2. Consider the following circuit to control a moving walkway. Every 2 seconds, the circuit examines two weight sensors and decides if the walkway will travel Northward or Southward or be turned off. There is a weight sensor in the North half of the walkway and a weight sensor in the South half of the walkway. If both sensors detect zero weight, the walkway is turned off. If the walkway is off and both sensors detect weight, the walkway remains...
