physics help………?
1.) A 2.0 Kg pail rest on a scale. Water is pored into the pail from a height of 1.5 meters at a rate of 100 g/s.
a.) What is the reading on the scale in kg one minute after the pouring began?
b.) The puring stops at one minute, what is the reading on the scale afterwards?
2.) A 5.0 kg object is dropped on a spring from a height of 2 meters. If the maximum compression fo the spring is 40 cm, what is its force constant?
3.) A force of 2 Newtons is needed to push 100 g jack in the box into its box. An operation in which the spring is compressed 10 cm. What will be the maximum speed of the jack in the box when it pops out.
4.) A neutron of mass (1.67 x 10^-27)kg and speed (1.00 x 10^5)km/s collides with a stationary deuteron of mass (3.34 x 10^-27)kg. The two particles stick together. What is the speed of the composite particle?
In D assuming that no energy is lost in the collision, the energy of the system must be constant. so since the composite particle is three times the mass of the impacting item, the resulting speed must be 1/3 of the neutron i.e. 1.67 x 10^4 m/s
