Question

At t=0 s a particle is located at -4 m, has a velocity of 0 m/s, and is moving with a constant acceleration of 0.25 m/s2 south. Use this information to help you fill in the table below. Then, in the diagram below the data table, place each dot where the particle will be at the indicated time. Let south be the positive direction & north be the negative direction. The units for the number line are meters

I need velocity for when t sec is 0,2,4,6,8

Explanation / Answer

The initial : u=0 m/s a=0.25m/s2 By using the formula: s=ut+1/2*at^2 by putting the values in the equation we get at t=0 : position=-4m at t=2 :s=.25*4/2=.5 => position=-4+.5= -3.5 similarly at t=4: position=-2 at t=6: position= 0.5 at t=8: position= 4
