  3. Use your kinematic equations. Start by writing what you know (initial velocity is 0, time is 0.3 seconds, and distance traveled can be measured from the drawing). Once you know three things, you can use your kinematic equations to solve for the other two (details here: https://www.aplusphysics.com/courses/regents/videos/KinEqns_Reg/KinEqns_Reg.html)
  4. How do you calculate magnitude of acceleration of a cart during the time interval t=0 second to t=0.30 second? (#7 on p 18 of workbook)
  5. Sorry BrandyBoy72 ... but you got your circumference and area formulae mixed up! Circumference of a circle = 2πr not 2πr2 !! Area of a circle = πr2 Xavier June 2021
