An object is moving with velocity (in ft/sec) v(t) = t² - 4. Find the displacement and total distance travelled from to displacement: ft total distance travelled: ft.
a) Displacement: -4 ft, Total distance travelled: 4 ft
b) Displacement: -8 ft, Total distance travelled: 8 ft
c) Displacement: -16 ft, Total distance travelled: 16 ft
d) Displacement: -32 ft, Total distance travelled: 32 ft
