a 1. For their inaugural journey, Serena and Evan aim a laser rangefinder at the moon. How long would it take for laser beam (constant velocity, v3.0 x 10 m/s) to go to the moon and back if the distance to the moon is 3.8 x 10º m? (2.5 s) 2. As he traverses the foreboding landscape at a constant speed of 100 km/h using his rocket pack, Owen sneezes, causing him to momentarily shut his eyes for 0.5 s. How far does he travel in that time? If a massive carnivorous Slaarg suddenly emerges from its cave 15 m away from Owen's initial pre-sneeze position, does Owen become a tasty snack? (13.9 m, no) While escaping from hostile Borgs, Kennedy and Abi put on the afterburners of their reconnaissance craft, accelerating in a uniform way from 140.0 m/s to 160.0 m/s in 4.8 s. How far has their craft moved in this time? Sketch the d-t. v-t and a-t graphs, and calculate the area under the v-t graph to show that this also gives their displacement (720 m)
