Question 1
Read the scenario carefully
Scenario 1: A runner is racing in a 10-kilometer (km) race. The runner travels the first 2
km in 12 minutes (min). Then the runner stops for 2 min to have a drink of water. He
begins running again, and covers the next kilometer in 5 min. The following 3 km have
the same pace: 6 minutes per kilometer (min/km). The runner again pauses to tie his shoe;
he is paused for 1.5 min. He has 4 remaining km to go. When he starts running again, he
runs 1 km in 5 min, but the remaining 3 km are each 1 min slower than the one before (6
min, 7 min, and 8 min, respectively). Create a distance-time graph to show the runner's
speed
Construct a distance-time graph to show how the object(s) in your scenario move(s) over
time. Remember that the y-axis represents the distance traveled by an object, and the x-
axis represents time. Include the appropriate units on your graph.

A33.1 g copper object is launched from a 1.5 m 30° steel incline positioned on the floor by being pulled up a string attached to a 50.0 g mass suspended vertically over a pulley. the object is projected towards a glass table where it lands when it is at the point along its trajectory with the lowest speed. it comes to a halt when it clears the opposite edge of the table. it then falls and lands on 9 physics texts each 5 cm thick that are stacked on the floor on the opposite side of the table. assume that the table does not have a ledge and the rectangular object experiences 0.05 n of air resistance as it falls towards the books. how far and how long did the object travel and how fast does it hit the books. assume that at the moment the copper object leaves the incline, the massless string and ideal pulley break off
