A Volvo moving at a constant speed of 20 m/s passes a Saab waiting at a red light just as the light turns green. If the Saab begins from rest and accelerates at 2 m/s?: a. How far does the Saab travel before drawing even with the Volvo?
b. How fast is the Saab traveling at this point?
c. On a single displacement vs time axis, graph the displacements of the Volvo and Saab.

How would doubling the made of an object change the objects potential energy

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
