You shoot an arrow from a compound bow straight up into the air, and it goes 7.6 m above the height you shot it from before it falls back down. If you now shoot the arrow at a 22° angle above the horizontal, what will its new maximum height be?

You are sitting on the beach and wondering about the properties of mechanical waves. describe them in terms of ocean waves.

The pressure proportional to the area a- inversely b- directly c- increase d-decrease

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^.
