2- What is the kinetic energy in (N. m) and Joules of a 4Kg bowling ball rolling down a bowling lane at 10 m/s? compare this energy with that of a 250g baseball traveling 50
m/s. which object would hurt more if it hit you (i. e., which object has the greater kinetic
energy)?

Calculate the mass of an object that has a momentum of 100kg x m/sec and velocity of 4 m/sec
