An iron block with a mass m¡ = m/s. It collides with a copper block whose mass is m2 = 9.20 kg. The collision is inelastic so the blocks stick together, due to Velcro on the surfaces of the blocks. After the collision, the blocks continue moving and compress a spring with a spring constant k = 5000 N/m. How many centimeters will the spring be compressed from its equilibrium position? 4.80 kg, is flying through the air with a speed of 7.50 m2 m1 wwl AX

A 1.2 kg glider moving at 3.0 m/s [right] undergoes an elastic head-on collision with a glider of equal mass moving at 3.0 m/s [left]. The collision is cushioned by a spring whose spring constant, k, is 6.0 x 104 N/m. Determine the compression in the spring when the second glider is moving left at 1.6 m/s.

A 5.00-g bullet moving with an initial speed of vi = 390 m/s is fired into and passes through a 1.00-kg block as shown in the figure below. The block, initially at rest on a frictionless, horizontal surface, is connected to a spring with force constant 860 N/m. The block moves d = 5.60 cm to the right after impact before being brought to rest by the spring a) Find the speed at which the bullet emerges from the block.=----m/s b) Find the amount of initial kinetic energy of the bullet that is converted into internal energy in bullet–block system during the collision. =-------J

4. In an elastic head-on collision, a 0.60 kg cart moving at 5.0 m/s [E] collides with a 0.80 kg cart moving at 2.0 m/s [W]. The collision is cushioned by a spring (k = 1,200 N/m). i. Determine the velocity of each cart after the collision. ii. Determine the maximum compression of the spring.

A mass m1 = 10.5 kg, with initial velocity V0 = 12.5 m/s, strikes a mass-spring system m2 = 7.25 kg, initially at rest but able to recoil. Assume the spring is massless and the surface horizontal and frictionless. See the figure below. If the collision is completely elastic, what are the final speeds V1 and V2 of m1 and m2, respectively?

A 1.90 g bullet, traveling at a speed of 423 m/s, strikes the wooden block of a ballistic pendulum. The block has a mass of 228 g.   (a) Find the speed of the bullet/block combination immediately after the collision.m/s(b) How high does the combination rise above its initial position?m

A 142 g baseball moving with the velocity of 31.5 m/s toward a spring that has the spring constant of 1450.N/m. When the baseball comes to rest compressing the spring, how much is the spring compressed?

2. A 1.2 kg cart moving at 6.0 m/s [E] collides with a stationary 1.8 kg cart. The head-on collision is completely elastic and is cushioned by a spring. a) Find the velocity of each cart after the collision. Add Units and directions

two balls, m1= 2 kg and m2= 5 kg, can slide without friction on a rod. a spring with a rigidity coefficient of k= 1000 N/m was connected to the ball with a mass of m2. since v1= 14 m/s and v2= 0; a) find the maximum compression that will occur in the spring when the balls collide. b) find the final speed of the balls after the collision. m, m2 k V1
