Bargoon launched a potato straight up into the air with a speed of 16.67m/s(up). What was the speed of the potato one second later??
Vf = Vi + (-9.8m/s^2)*t whereVf is the velocity at any time, Vi = 16.67m/s and t = 1 ......so we have
Vf = 16.67/m/s + (-9.8m/s^2) (1s) =
Vf = 16.67m/s - 9.8m/s =
Vf = 6.87m/s [ the potato is still rising after 1 sec ]
