how much momentum will a ball of a mass 10 kg transfer to a floor if it falls from a height of 80 cm. assume its downward acceleration to be 10 ms-2​

Answer»

mass=10kghieght=0.8mg=10m/s^2u=0v=?now from NEWTON's THIRD equation of MOTION v^2-u^2=2asv^2-0=2x10x0.8v^2=16v=4m/snow,momentum=mass X velocitymomentum=10x4momentum=40kgmshence,the momentum of the body is 40 KGMS
