A ball is thrown up in the air, and it falls back down to the ground. The height, ℎ
,of the ball above the ground over time, 𝑡
,is shown on the graph by the blue line. The red line is a tangent to the blue line at 𝑡 =1s
.What is the speed of the ball at 𝑡 =1 s?
5 m/s
10 m/s
15 m/s
A fish swims a distance of 15 m to the left at an average speed of 2 m/s and then immediately turns around and swims half this distance to the right. The time that passes while all this occurs is 12 s,as shown in the diagram. In this question, consider displacement to the left as positive.
What is the average velocity of the fish over the 12 s that the fish moves for?
0.625 m/s
1.875 m/s
1.25
