Which two of these equations are correct about this position function y(t) = -4.5t + 0.2t?
Select 2 choice(s)
O v(t)
At the maximum displacement:
0 = - 9t - 0.2
= - 9t + 0.2t
At the maximum displacement:
0 = - 9t + 0.2t
O v(t) = 9t + 0.2
O v(t) = -9t + 0.2
At the maximum displacement:
0 = - 9t + 0.2
