An automobile traveling along a straight road increases its speed from 32 ft/s to 48 ft/s in 180 ft. If the acceleration is constant, how much time elapses while the auto moves the 180 ft? Answer in units of s

a racing car has a uniform acceleration of 4ms-1.what distance will it covers in 10s after start?

A lead shot is projected from the ground level with a velocity U, at an angle O, to the horizontal. Given that the times t, for the lead shot to reach its maximum height as t=UsinO/g. Where g is acceleration due to gravity. Show that H reached by the body is Hmax=U^2sin^2O/2g

Steps: Determine the problem:  How do mass and length affect the period of a simple pendulum? Make a hypothesis:  Make a prediction of how you expect each mass and length to change the period. Test your hypothesis: Build a simple pendulum (see: you must see the videos:  https://www.youtube.com/watch?v=J-bIXf_xyAg     ) and record the results for each combination below. Test the results using the pendulum lab 2.03 simulation located at the PhET site:  https://phet.colorado.edu/sims/pendulum-lab/pendulum-lab_en.html Analyze the data for each case:  What were the effects of mass and of length on the period? Draw a conclusion:  Report the results from your analysis of the period. Comment, in a final paragraph, on your experience with the experiment.  How was it?  What did you learn about the pendulum?  About yourself in the doing of a real experiment? https://youtu.be/yVkdfJ9PkRQ In the attachement there is a notes from the chapter.

a particle has an acceleration of +6.24m/s^2 for 0.300s. At the end of this time, the particles velocity is +9.31m/s. What was the particles initial velocity?
