For the instant represented, corner a of the rectangular plate has a velocity va = 6.2 m/sec and the plate has a clockwise angular velocity w = 13 rad/sec. determine the magnitude of the corresponding velocity of point b. hint: use instant centers.

Which of these metals are magnetic?

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^.

Complete the sentence to describe the law of conservation of energy. the law of conservation of energy states that energy cannot be created
