Two technicians are discussing automatic transmission transaxles. technician a says that it is normal for a vehicle to move slightly when the gear selector is in the drive position with the brakes released .technician b say that the stator may be defective if the vehicle moves while in gear when the engine is defective if the vehicle moves while in gear when the engine is at idle speed. which technician is correct?

Visualize the problem and identify special cases first examine the problem by drawing a picture and visualizing the motion. apply newton's 2nd law, ∑f⃗ =ma⃗ , to each body in your mind. don't worry about which quantities are given. think about the forces on each body: how are these consistent with the direction of the acceleration for that body? can you think of any special cases that you can solve quickly now and use to test your understanding later? one special case in this problem is if m2=0, in which case block 1 would simply fall freely under the acceleration of gravity: a⃗ 1=−gj^.
