1. a ball of mass, m, swings through a height, h, of 0.03m toward a ball of mass, M =3m, which is initially at rest. If m has an initial speed, v, of 5 m/s and strikes M elastically, determine how high each ball rises afterward neglecting air resistance?

2. A bullet emerges from the muzzle of agun with a speed of 300m/s. The resultant force on the bullet, while it is in the barrel, is given by: F=400 N-1/3(4*10^5 N/s)t, where t is in seconds

a) calculate the time for the bullet to travel the lenght of the barrel, assuming the force is zero at the end of the barrel?

b) find the impulse of the force ?

c) find the mass of the bullet?
