If at t=0s , the object is 12m to the left of the originn, what is its position at t = 5 s? CHoices: 24 m 60 m 4 m 36 m 12 m

1. For their inaugural journey, Serena and Evan aim a laser rangefinder at the moon. How long would it take for a laser beam (constant velocity, v= 3.0 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)

Objects A and B have positions as functions of time given by (t) = ati + yt² j and TÂ(t) = ßti + ot², respectively, where • α = 2.27 m/s 3.27 m/s² Ύ 7 В 2.61 m/s • J = -1.95 m/s² t= = 0.4 s = = Determine the distance |A7| between them at t = 0.4 s.

To start an avalanche on a mountain slope, an artillery shell is fired with an initial velocity of 320 m/s at 45.0° above the horizontal. It explodes on the mountainside 37.0s after firing. What are the x and y coordinates of the shell where it explodes, relative to its firing point? x = 8371.99 y = 1663.89
