To solve this problem, apply the formulas:
s = Vo*t + (1/2)*a*t^2
Vf = Vo + at
The provided values include:
Vf = final velocity =?
Vo = initial velocity = 1.4 m/s
a = acceleration = 0.20 m/s^2
s = displacement = 100m
Now perform the following calculations:
<span>100 = 1.4t + (1/2)*0.2*t^2
</span>t = 25.388s
and
Vf = 1.4 + 0.2(25.388)
Vf = 6.5 m/s
Thus, the sought answer is 6.5 m/s
Answer:
1) Engage in regular physical activity. Regular exercise offers numerous advantages, including bolstering heart health and enhancing blood flow. It aids in weight maintenance and reduces cholesterol and blood pressure, thereby decreasing heart disease risk.
2) Limit alcohol consumption. Excessive alcohol intake can elevate blood pressure. It also contributes additional calories, potentially leading to weight gain, both of which increase the chance of heart disease. Men should restrict their intake to a maximum of two drinks daily, while women should have only one.
3) Manage cholesterol and triglyceride levels. High cholesterol can block arteries, heightening the risk of coronary artery disease and heart attacks. Adjustments in lifestyle can effectively decrease cholesterol levels. Triglycerides, another fat type in the bloodstream, can also contribute to coronary artery disease risk, particularly among women.
Sarah set a goal to reduce her juice consumption, researched recommended daily water intake, and chose a substitute to replace juice consumption.
Hope this helps!
