Three objects are fired into the air; and the drawing shows the trajectories of the projectiles, labeled A, B, and C. Which projectile is in the air for the greatest amount of time? 12 TO 15 30 30 35 * (m) O Projectile A, because it travels higher than the other two objects O All three objects spend the same amount of time in the air. O Projectile C, because it must travel more slowly to reach the ground at the same place as object A O Projectile B, because it travels farther horizontally than the other two objects O Projectile B, because it crosses the path of object AYou step onto a hot beach with your bare feet. A nerve impulse, generated in your foot, travels through your nervous system at an average speed of 141 m/s. How much time does it take for the impulse, which travels a distance of 1.41 m, to reach your brain? Number i UnitsThe three-toed sloth is the slowest moving land mammal. Assume that on the ground the sloth moves at an average speed of 0.0210 m/s. considerably slower than the giant tortoise, which walks at 0.0258 m/s. After 5.60 minutes of walking, how much further would the tortoise have gone relative to the sloth? Number i Units
