A light spring is attached to the more massive block, and the blocks are pushed together with the spring between them (Fig. P8.7).

The superball collides with the floor, rebounds, and smacks the marble, which moves back up. How high does the marble go if all the motion is vertical? How high does the superball go?arrow_forward
- Review. There are (one can say) three coequal theories of motion for a single particle: Newtons second law, stating that the total force on the particle causes its acceleration; the workkinetic energy theorem, stating that the total work on the particle causes its change in kinetic energy; and the impulsemomentum theorem, stating that the total impulse on the panicle causes its change in momentum. In this problem, you compare predictions of the three theories in one particular case. A 3.00-kg object has velocity 7.00jm/s. Then, a constant net force 12.0iN acts on the object for 5.00 s. (a) Calculate the objects final velocity, using the impulsemomentum theorem. (b) Calculate its acceleration from a=(vfvi)/t. (c) Calculate its acceleration from a=F/m. (d) Find the objects vector displacement from r=vit+12at2 (e) Find the work done on the object from W=Fr. (f) Find the final kinetic energy from 12mvf2=12mvfvf. (g) Find the final kinetic energy from 12mvi2+W. (h) State the result of comparing the answers to parts (b) and (c), and the answers to parts (f) and (g).arrow_forwardA hockey puck of mass 150 g is sliding due east on a frictionless table with a speed of 10 m/s.
