v(0.5) = 30.1
v(1.5) = 20.3
So, 20.3 <= v <= 30.1
not sure why the warning about negative quantities ...
19. The velocity of an object fired directly upward is given by V = 35 – 9.8t, where t is time in seconds. Which inequality describes the velocity when t is between 0.5 and 1.5 seconds? (HINT: Remember that when you multiply an inequality by a negative number, you must switch the direction of the inequality.)
Please explain how to do
