Answer:
It takes 1600 seconds or hours to travel a distance of 20 km.
Explanation:
Given:
Speed of the motorcycle,
Distance traveled by the motorcycle,
We know that,
∴
Plug in 20 km for and 45 km/h for . Solve for time.
⇒ Time =
Therefore, the time taken to travel a distance of 20 km is 1600 seconds or hours.
== You're pushing the load <u><em>straight</em></u> along the horizontal surface at a <u><em>constant speed</em></u>.
== The speed and direction of the load are not changing, so there is <u><em>no acceleration.</em></u>
== From Newton's 2nd law of motion, we know that F = m A . Since A=0, F must also be zero. That means <em>NO NET FORCE</em> is acting on the load.
== But how can that be ? You're pushing it with 90 N !
== The NET force is zero. So something else must be pushing the box, also with <em>90 N of force, exactly opposite to YOUR force, </em>and they add up to zero.
== THERE's your force of friction !
