1. Every morning, an athlete jog around a 400-m oval track six times in 30 minutes. What is the athlete’s (a) average speed and (b) average velocity? 2. A body moving with a constant acceleration in a straight line was first observed to be moving at 4.5 m/s. After 10 seconds, it was moving at 6.8 m/s. Find its acceleration.

You and a friend (alex) are at a a tree-top adventure park .. . part of the course requires you to climb up a rope. you both climb the same rope in the same amount of time. however, the tension in the rope is greater when alex climbs. who did the most work? alex did - more tension means more force - more force means more work was done you did - less tension means less force - less force means more work was done to find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? when more work was done, the couch was moved less. when more work was done, the couch was moved further. when more work was done, the couch wasn't moved at all. when more work was done, the couch was moved the same distance.

Why are graphs useful when interpreting data

Afrequency generator sends a 550 hz sound wave through both water and ice. what is the difference in wavelength between the wave produced in ice and the wave produced in water?
