- 1. A particle has an initial speed of 60 kph. If it experiences a deceleration of a = (- 6t ^ 3 + 4t) * m / s * 2 where t is in seconds, determine its velocity, after it has traveled 100 m in m/s. How much time does this take in second(s)? 2. The dragster starts from rest and travels along a straight track with an acceleration-deceleration described by the graph. Construct the v-s graph for 05. 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.Kindly provide complete formula and solution During a test run on an airport runway, a new race car reaches a speed of 115.52m / s from a standing start.

- I know the answer is c but can you please explain whyA 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?When Sam drove at 9.5 m/s on university blvd, she passed her friend, Jess who was riding a bike at 5.0m/s. As Sam was passing Jess, she started to slow down while Jess kept her constant speed. So Jess caught up to Sam after 3 seconds. a.) Determine the distance traveled by Jess when she caught up to Sam.
