? A tractor was moving without changing its velocity. At one point during this time, V = 9 mph east. At a later point during this time,V = 7 mph east.
? While a walrus was traveling with a constant speed in a straight line, it sped up.
? While a sloth was in motion with an unchanging velocity, it changed the direction it was going.
? A horse moved in one direction with a constant speed. At one moment while it was moving, the following data were taken: x = 81 km, vx = 0 km/h, ax = 0 km/h2.
? A stone was moving through the air with a constant velocity of 18 ft/s south and an acceleration magnitude of 4 ft/s2
? While a leopard was moving with constant V , it slowed down.
