In this given problem, to solve for the acceleration we have to
assume that the acceleration is constant. This assumption helps us understand
that the velocity of Dave follows a linear increase and hence we can use the
formula below for calculating the acceleration:
a= (Vf – Vi) / t
where
Vf = final velocity = 7.0 m / s
Vi = intial velocity = 3.0 m / s
t = time elapsed = 10 s – 5 s = 5 s
Substituting the known values into the equation:
a = (7.0 m / s – 3.0 m / s) / 5 s
a = 0.8 m / s^2
Answer:
<span>D. 0.8 m/s2</span>
Answer:
a. 66.1798kg
b. 92.47%
Explanation:
His weight had been stable at 135 pounds until the past 6 months, in which he has experienced an involuntary weight loss of 10 pounds. He is 67 inches tall and his current BMI is 19.5. He complains of a poor appetite and being overly weak and tired. He also complains of cracks at the corners of his mount and a chronic sore throat which concerns him, given his cancer history. His usual diet is fairly consistent. He states that he rarely eats breakfast because he starts work at 6 a.m. He eats two deli meat sandwiches, "usually pastrami or salami," and a soda at 10 a.m., and may eat a candy bar in the afternoon when he gets off work. He often prepares frozen dinners or pizza at home in the evening and routinely drinks "about 4 or 5 beers" before going to bed. Occasionally he will cook a roast and mashed potatoes. He occasionally will have milk with cereal but rarely eats vegetables or fruit. He would like to know which vitamin supplement will give him energy.1.What is Samuel’s Ideal Body Weight? What is his current percentage of ideal body weight?
Extracting the parameters from the above statements
we can calculate ideal body weight in men as
50 + (0.91 × [height in centimeters − 152.4])
convert his height in inches to centimeters
67inches=170.18
50+(0.91*(170.18-152.4)
66.1798kg
What is his current percentage of ideal body weight?
61.2/66.178*100%
92.47%
