Ablock of mass 0.510 kg is pushed against a horizontal spring of negligible mass until the spring is compressed a distance x. the force constant of the spring is 450 n/m. when it is released, the block travels along a frictionless, horizontal surface to point circled a, the bottom of a vertical circular track of radius r = 1.00 m, and continues to move up the track. the speed of the block at the bottom of the track is va = 13.7 m/s, and the block experiences an average frictional force of 7.00 n while sliding up the track. what is x? and what is the speed of the block if it reaches the top?

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^.
