Use the format of "if . . . then . . . because . . . ” and be sure to answer the lesson question "How can Newton's laws be experimentally verified?” specific to Newton’s first law.

Given the position vector of the particle r(t)=(t+1)i+(t^2−1)j+2t k, find the particle's velocity and acceleration vectors at t=1
