A first block with m(1)=2.00 kg lies at rest on a frictionless table. An ideal spring, with a spring constant of 100 N/m is attached to the wall and to the block. A second block with m(2)=0.50 kg is placed on top of the first block. The first block is gently pulled to a position x = + A and released from rest. There is a coefficient of static friction of 0.45 between the two blocks. (a) What is the...
In the figure, a 5.00-kg block is moving at 5 m/s along a horizontal frictionless surface toward an ideal massless spring that is attached to a wall.

8.67 Blocks A (mass 6.00 kg) and B (mass 14.00 kg, to the right of A) move on a frictionless, horizontal surface. Initially, block B is moving to the left at 0.500 m/s and block A is moving to the right at 2.00 m/s. The blocks are equipped with ideal spring bumpers.

A 0.60 kg block rests on a frictionless horizontal countertop, where it is attached to a massless spring whose k-value equals 18.0 N/m. Let x be the displacement, where x = 0 is the equilibrium position and x > 0 when the spring is stretched. The block is pushed, and the spring compressed, until xi = −4.00 cm. It then is released from rest and undergoes simple harmonic motion. (a)What is the block's maximum speed (in m/s) after it is...
A 2.00-kg block lies at rest on a frictionless table. A spring, with a spring constant of 100 N/m, is attached to the wall and to the block. The second block of 0.50 kg is placed on top of the first one. The 2.00-kg block is gently pulled to a position x = + A and released from rest.
