Homework SourseThe displacement in meters of a particle moving in a straigh
The displacement (in meters) of a particle moving in a straight line is given by the equation of motion
s = 9/t^2,
where t is measured in seconds. Find the velocity of the particle at times
t = a, t = 1, t = 2, and t = 3.
s = 9/t^2,
where t is measured in seconds. Find the velocity of the particle at times
t = a, t = 1, t = 2, and t = 3.
Solution
s=9/t^2 v=ds/dt v = -18/t^3 at t=a v(a)=-18/a^3 at t=1 v(1)=-18 at t=2 v(2) = -9/4 at t=3 v(3)= -2/3
