Explanation & Answer
Hey dude😊 I have the solutions ready as promisedPlease find the two attached .doc files with one containing the solutions and the other containing the concepts
1. The following kinematics formulas are useful in answering the questions
𝑖) 𝑣 = 𝑢 + 𝑎𝑡
1
𝑖𝑖) 𝑠 = 𝑢𝑡 + 𝑎𝑡 2

a) To solve this question we need to investigate if there is a direction change in the
velocity within the given time interval. This can be seen by just looking at the graph
b) To determine the time the velocity changes from positive to negative and vice versa,
we need to equate the velocity function to 0
c) Integrating over a g...
