Find the positions of the two masses at any subsequent time t (before either mass returns to the table) and describe the motion.
Compute the momentum of the bullet
The bullet becomes embedded in the block. If the bullet-block system compresses the spring by a maximum of 88.0 cm, what was the speed of bullet at impact with the block.
How might a magician make the Statue of Liberty disappear? Imagine that you are sitting with some spectators on a circular platform that, unknown to all of you, can rotate very slowly. It is evening, and you can see the Statue of Liberty a short dist..

An inflated rubber balloon is rubbed with a wool cloth till an excess of a billion electrons is on the balloon. What is the magnitude of the charge on the balloon.
It is said that Galileo discovered a basic principle of the pendulum - that period is independent of the amplitude - by using his pulse to time the period of swinging lamps in the cathedral as they swayed in the breeze. assume that one oscillation..
A dockworker applies a constant horizontal force of 79.0N to a block of ice on a smooth horizontal floor. The frictional force is negligible. The block starts from rest and moves a distance 15m in a time 4.50s. What is the mass.
A tight guitar string has a frequency of 540Hz as its third harmonic. What will be its fundamental frequency if it is fingered at a length of only 56% of its original length?
The two forces in each pair could have different physical origins (for instance, one of the forces could be due to gravity, and its pair force might be due to friction or electric charge).
A charge of +q is situated at the origin, while an identical charge is located on the x axis at x = 0.58 m. A third charge of +4q is located on x axis at such a place that the net electrostatic force on the charge at origin triples.
A rocket ship at rest in space gives a short blast of its engine, firing 90 kg of exhaust gas out the back end with an average velocity of 700 m/s.
