Simpson drives his car with an average velocity of 45.2 km/h to the east. How long will it take him to drive 149 km
on a straight highway?
Answer in units of h.
How much time would Simpson save by
increasing his average velocity to 95.9 km/h
to the east?
Answer in units of min

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^.
