Bears and coyotes both consume large plant-eating mammals such as deer. When the deer are in short supply, bears and coyotes may fight over the prey. This type of biological interaction is called

A particle's velocity is described by the function vx=kt2m/s, where vx is in m/s, t is in s, and k is a constant. The particle's position at t0=0s is x0 = - 8.10 m. At t1 = 2.00 s, the particle is at x1 = 8.00 m.
