- what is the magnitude of the impulse given to the ball ?The head of a golf club experiences a 3.9% change in linear momentum upon impact with a golf ball. Estimate the speed of the 47 g ball in m/s if the club speed and mass prior to impact are 31 m/s and 400 g, respectively.Sphere A of mass 0.9 kg travels with an initial velocity vA =11 m/s as shown and strikes the 2.8-kg sphere B which travels with a velocity VB =6 m/s. If the coefficient of restitution is 0.4, determine the speed of sphere B after impact. Give your answer in m/s. VA VB A B
- A snowball of mass 2 kg is rolling on a flat surface with a speed of 5 m/sec. Assume there is no friction. It collects more snow and now has a mass of 3 kg. What is it’s speed now?If two particles have equal kinetic energies, are their momenta equal?A person that has a mass of 83 kg stands in the middle of a frozen pond with a radius of 11 m.Because of the frictionless nature of the ice, they are unable to get to theother side of the pond. So, the person throws their textbook that has a mass of2.3 kg horizontally towards one side of the pond, with a speed of 7.5 m/s. How fast does theperson slide along the ice?
