- 5. Draw a distance vs. time graph for Melinda’s journey. Her home is located at 0 meters.Melinda is riding her bike over to her friend Sara’s house to complete an assignment. Her friend lives 5 km away. She accelerates away from her home for250 m in the next 2.5 minutes. She then rides at a constant speed of 300 m/min for 15 minutes. Melinda sees Sara’s house approaching so she slows downuntil she reaches her destination in the next 2.5 minutes. She stays at Sara’s house for 30 minutes while they work on the assignment. It is time to go home,Melinda rides home at a steady speed of 250 m/min for 10 minutes. Melinda is getting tired so she slows down for 250 m during the next 5 minutes thenstops for 2.5 minutes to have a drink. Realizing it’s getting late, she had to speed up 1 km in the next 5 minutes then rides at a constant speed of 300 m/minfor 2.5 minutes. Almost home, she decelerates for the next 10 minutes until she reaches her house.2- A) Estimate how long it took King Kong to fall straight down from the top of the building (475 mm high).

- 14. The speed of a nerve impulse in the human body is about 100 m/s. If you accidentally stub you toe in the dark, estimate the time it takes the nerve impulse to travel to your brain. (Assume that you are approximately 1.70 m tall and that the nerve impulse travels at uniform speed.)1. The cheetah can reach a top speed of 114 km/h. while chasing its prey in a short sprint, a cheetah starts from rests and runs 45 min in a straight line, reaching a final speed of 72 km/h. a. Determine the cheetah's average acceleration during the short sprint, and b. Find its displacement at t= 3.5 s O 4.4m/s2, 27m O 5.6m/s2, 56m O 1.2m/s2, 15m5. Kathy tests her new sports car by racing with Stan. Both start from rest, but Kathyleaves the starting line 1.00 s after Stan does. Stan moves with a constant acceleration of 3.50m/s2, while Kathy maintains an acceleration of 4.90 m/s2.(a.) Find the time at which Kathy overtakes Stan.(b.) Find the distance Kathy travels before she catches him.(c.} Find the speeds of both cars at the instant Kathy overtakes Stan.
- 2. Two cars are drag racing. The red car accelerates at a rate of 4.7 m/s', and the blue car at a rate of 3.9 m/s’. The blue car starts 1.5 s before the red. Find the time it takes for the red car to be at the same position as the blue car, how the cars have traveled, and how fast each is moving at this time.5. An “L" train leaves the Washington station on the blue line starting from rest and accelerating at a constant acceleration of 1.35 m/s² for 16.0 s. It runs at a constant speed for 85.0 s and then slows down at a rate of 3.00 m/s? until it stops at the Grand station. What is the total distance traveled by the subway train?
