Three elephant are staying on a very very strong bridge happens to have marks at every meter along the way almost like it was meant for setting up a physics problem elephant is standing at 4m and starts walking he walks for 30 second and after 30 seconds the elephant is place on the bridge marked 64 meters what us elephant speed

Phase changes are chemical changes. true or false

What is friction? how does it affect the motion of an object?

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^.
