Answer:
712.5 kg m/s
Explanation:
Work out the total momentum before the event (before the collision):
p = m × v
Massof Deon = 95kg
Velocity =7.5m/s
Mass of Chuck = 120kg
Velocity = 0m/s
Momentum of Deon before = 95 × 7.5 = 712.5 kg m/s
Momentum of Chuck before = 120 × 0 = 0 kg m/s
Total momentum before = 712.5+ 0 = 712.5 kg m/s
Working out the total momentum after the event (after the collision):
Because momentum is conserved, total momentum afterwards = 712.5 kg m/s
Reflection and refraction are two different phenomenons. In case of reflection, wave bounces back into the same medium after incident with the interface of two mediums. Reflection will happen if surface is shiny as well as smooth. If surface is irregular, one will get diffused reflection. Refraction means bending of light when waves travel from one medium to another
The reaction time of Boris is t(r), so before that, Boris will not have jumped. Thus, H(b)(t) = 0
The vertical displacement will simply be
D(t) = H(a)(t)
