A projectile is launched from ground level with an initial velocity of v 0 feet per second. Neglecting air resistance, its heig
ht in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. Find the time(s) that the projectile will (a) reach a height of 288 ft and (b) return to the ground when v 0equals144 feet per second. (a) Find the time(s) that the projectile will reach a height of 288 ft when v 0equals144 feet per second. Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
Overtime is over 40 so subtract 40 from 54 and get 54-40=14 14 hours hovertime so multipliy usuall pay by 40 (since worked 40 normal hours) then add to overtime pay by 14 hours so
(13.5 times 40)+(13.5 times 1.5 times 14)= 540+283.5=823.5 answer is $823.50
