Q Next diagram shows relationship between aelocity and time of a body moving along shown path. Let me see physical touches in your answer, not just mathematical notes. O Find the average acceleration of the object during the time intervals (0-5) . (5-15) s (0-20) s i) Find the instantaneous acceleration at 2. 10s, 18s (ii) Find the displacement between (10-20) s. v (m/s) 8 6 4 2 I (s) 20 15 -2 -4 -6 -8 l

I need help with this question

Hi I am in phyiscs I and it has the problem a runner ran the marathon (approx. 26.1) in 2 hours and 57 min. What was the average speed of the runner in m/s? I understand that I would have to divide the total distance by the total time, but I'm not sure how they changed the miles to meters. Please detalied steps of how to solve this so I can understand it. Thank you!

A car is traveling due East at a rate of 36.2 kph and a train is due North at a speed of 74.70 kph and bound to meet at an intersection 1 km from the train and the car. Determine the acceleration of the car, if the car reaches the intersection 10 seconds ahead of the train. b. Determine the velocity of the car at the intersection.

A travels along a straight road. The following simplified graphbelow shows the car’s velocity over several time periods during20 seconds of travel. a) What was the average velocity of the car during the 16.0 – 20.0 s timeinterval? Answer to two significant digits. b) What was the instantaneous velocity of the car at time = 18.0 s? Answer totwo significant digits. c) Compare and explain your results from parts a and b.

In a women's 200m race, accelerating uniformly, Jane takes 2.50s and Irma 3.00s to attain their maximum speeds, which they each maintain for the rest of the race. They cross the finish line simultaneously, both setting a world record of 20.0s. a. What is the acceleration of each sprinter? a. Jane b. What are their respective maximum speeds? Show your COMPLETE SOLUTION a. Irma b. Jane b. Irma

You are on the planet Neptune and want to determine the acceleration due to gravity, g. You have a stopwatch and a toy gun that can launch a ping pong ball vertically upwards with an initial velocity of 7.5 m/s. Describe, in words, how you would perform an experiment to determine the acceleration due to gravity. Be sure to describe the variables you would measure, the equations you would use and the assumptions you would make. Make sure to include a diagram of the physical situation, label the unknown and known quantities with units, coordinate system in your answer.

a truck traveling At a stup light, at 15 m/s passes a caR 'as it Starts trom rest, The teuck. travels at constant velocity and the Car accelerates at 3 m/s% How much time does the caR take to catch we to the tRuck? a Please explain each step IN detail. Please Include. all equations With cleaR explanations. Thank you
