here is the question?
Two stationary ice skaters, denise and lauren are facing each other and use the palms of their hands to push each other in opposite directions. Denise with a mass of 50 kg, moves off in a straight line with a speed of 1.2m/s-1. Lauren moves off in the opposite direction with a speed of 1.5m/s-1.
a) calculate Lauren's mass
b) calculate the magnitude of the impulse that results that results in Denise's gain in speed.
c) calculate the magnitude of the impulse on lauren while the girls are pushing each other away.
d) what is the total momentum of the system of Denise and Lauren just after they push each other away?
e) would it make any difference to their final velocities if they push each other harder? explain.
Note: please put the formulas down at least and calculations. please use standarde internationale units(SI). ie. meters, kilograms, seconds, newtons etc.
