Two parts:
a) An object with an initial massmi=7and an initial velocityvi=6m/s making an angle of 40degrees with the +x axis has, after a time 4seconds, final velocityvf=3making an angle of 0degrees wrt -x. a) Determine the netforce acting on the mass corresponding toFnet=(pf-pi)/delta(t), needed toproduce that change in momentum. b) Now, assuming there is gravityplus a second, contact force acting on the mass, estimate themagnitude of the second contact force applied to the mass over thetime t seconds (using F(contact) +F(gravity) = F(net)) and draw thevectors demonstrating graphical addition.
b) An 6 kg mass, moving at an angle of 40degrees wrt the +x axis with an initial velocity magnitude|5| collides inelastically with an 8kg mass, moving at an angle of 50 degrees wrt the+x axis and with an initial velocity magnitudev1= 3m/s. Determine a) the angle thatthe composite object makes with the axis of your choice, b) themagnitude of the final velocity of the single object, as well as c)the heat generated in the collision.
