Answer:
V2 = -25.93 m/s
Explanation:
First of all, we know that;
Momentum = mass x change in velocity
Thus;
Momentum = m(v2 - v1)
Also, we know that;
Impulse = force x time
And also that;
Momentum = Impulse
From the question, m = 0.145kg and V1 = 32m/s while impulse = -8.4 N.s
Thus;
0.145(v2 - 32) = -8.4
Now,
0.145v2 - 4.64 = -8.4
0.145v2 = -8.4 + 4.64
0.145v2 = -3.76
v2 = -3.76/0.145
= -25.931 m/s and to two significant figures gives -25.93 m/s
Explanation:
1) If you spot something you think might be hazardous in your workplace, report it to your employer and safety rep straight away. Your employer should then decide what harm the hazard could cause and take action to eliminate, prevent or reduce that harm. Read more about risk assessments .
2) Complex hazards are understood as various combinations of sources of hazards that lead to the accident occurrences. ... The term "natural-technological" applies to both human-induced intensification of natural risks and any accidents in the technosphere triggered by natural processes or phenomena.
3)Risk Evaluation : To determine who may be harmed. Risk Control : Taking preventive measures to control the impact of risk.
In general, to do an assessment, you should:
Identify hazards.
Determine the likelihood of harm, such as an injury or illness occurring, and its severity. ...
Identify actions necessary to eliminate the hazard, or control the risk using the hierarchy of risk control methods.
