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.arrow_forward6-10 are wrong. Please tell me the right answers.arrow_forward

- 1. In this problem assume the positive direction is up and the negative direction is down and that the floor is zero position. a. A ball starts 1.5 m above the floor. The ball is dropped, it hits the floor and bounces. Make a sketch of the position vs. time graph you would expect as the ball falls, hits the floor, bounces back up, then falls to hit the floor again. Which kinematic equation describes the position of the ball, as time passes, while it is in the air? b. Make a sketch of the velocity vs. time graph for the ball as it falls, hits the floor, bounces back up, and falls to hit the floor. Which kinematic equation describes the velocity for the ball, in terms of time, while it is in the air? c. Make a sketch of the acceleration vs. time graph for the ball as it falls, hits the floor, bounces back up, and falls to hit the floor. What will be the acceleration of the ball as it falls? What will be its acceleration as it rises?arrow_forwardA toy train rolling on a straight stretch of tracks, initially going 0.31 m/s slows uniformly to 0.14 m/s in 17 s.
