A car is traveling with a constant speed along a road that has a form of a square. The car starts at the beginning of one side of the square and covers two and a half sides. The speed of the car is 50 miles/hour. What is its average velocity ? plz also show step by step on how you acquired the formula you are using to solve this problem. Thank You!!!!
You start out by driving 82 miles north in 4 hours and 36 minutes, and then you stop and park for a while. Finally you drive another 60 miles south in 3 hours and 11 minutes. The average velocity for your entire trip was 2.26 miles per hour to the north. How much time did you spend parked?1 hour 56 minutes 3 hours 53 minutes 0 hours 58 minutes 9 hours 43 minu
Bill and Amy want to ride their bikes from their neighborhood to school which is 21.3 kilometers away. It takes Amy 38 minutes to arrive at school. Bill arrives 23 minutes after Amy. (Add Amy's time with 23 min to get Bill's time.) How much faster (in meters/second) is Amy’s average speed for the entire trip? m/s (Convert km to m and min to sec)
pls. answer with FBD pls. A car accelerates uniformly from zero to 10m/s2 in 6 seconds starting from rest. During the next 3 seconds, the car decelerates at a constant rate of 2m/s2. Compute the total distance traveled after 9 seconds.
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.

A motorcycle begins at rest at t0 = 0 seconds. The motorcycle starts moving, and eventually covers a distance d = 840 m, in a time tf = 189 s. In a coordinate system with north being the positive x-direction, the motorcycle's motion is in the northern direction (see figure). 1. What was the motorcycle's average speed, vavg, during this period, in meters per second? 2. What was the motorcycle's displacement in the northern direction during this period, in meters?
