Question 26

Multiple Choice

Your name is Francesca Dragonetti (an assistant of Galileo Galilei) and, to impress your boss, you toss a weight upward at 32 feet per second from the top of the Leaning Tower of Pisa (height 185 ft) . Neglecting air resistance, find the weight's velocity and the height of the weight above the ground as a functions of time in seconds. ?


A) v(t) =10tv ( t ) = 10 t , s(t) =185+32t5t2s ( t ) = 185 + 32 t - 5 t ^ { 2 }
B) v(t) =32+32tv ( t ) = 32 + 32 t , s(t) =185+32t+16t2s ( t ) = 185 + 32 t + 16 t ^ { 2 }
C) v(t) =3232tv ( t ) = 32 - 32 t , s(t) =32t16t2s ( t ) = 32 t - 16 t ^ { 2 }
D) v(t) =3232tv ( t ) = 32 - 32 t , s(t) =185+32t16t2s ( t ) = 185 + 32 t - 16 t ^ { 2 }
E) v(t) =32tv ( t ) = 32 t , s(t) =32t16t2s ( t ) = 32 t - 16 t ^ { 2 }
