How much work is done when a 70kg person climbs a ladder meters tall?
The work done by a 70kg person climbing a ladder depends on the height of the ladder, but can be calculated using the formula work = force x distance. The force is the person's weight (70kg x 9.8m/s^2) and the distance is the height of the ladder.
What force is necessary to accelerate at 70kg object at a rate of 4.2 minutes per seconds?
To accelerate a 70kg object at a rate of 4.2 m/s^2, you would need a force of 294 Newtons. This is calculated using Newton's second law, F = m*a, where F is the force, m is the mass of the object (70kg), and a is the acceleration (4.2 m/s^2).
15m long cantilever beam that is fixed in a wall and a person that weighs 70kg is standing at the free end of it what moment is that person's weight applying about the fixed support?
BM = Fxd = weight x gravity x distance 70 kg X 9,81 m/sec2 x 15 m = 10300,5 Nm = 10,3 kNm
How much force is needed to brace yourself in a car crash?
3 mph= 30x(1909m/36000s) = 13.3 m/s F= 70kg x (13.3 m/s)^2 /2x 0.02m = 31,000 Kg
How many kilos in 70 pounds?
1 kilogram = 2.2 pounds so 70kg X 2.2 = 154 lbs The formula to convert kg to lbs70 kg* 2.2046 lbs 1 kg = 154.3235835 lbs
What is the mass in kilograms of an adult weighing 11 stone?
To convert weight from stones to kilograms, you can multiply the weight in stones by 6.35. So, an adult weighing 11 stones would weigh approximately 70 kilograms (11 x 6.35 = 69.85 kg).
What is a persons weight in newtons that has a mass of 70 kilograms?
A person with a mass of 70 kilograms would weigh approximately 686 Newtons on Earth. This is calculated by multiplying the mass in kilograms by the acceleration due to gravity, which is approximately 9.81 m/s^2.
If crystal salt has a mass of 0.12 g how many NaCl formula units does it have?
To calculate the number of NaCl formula units in 0.12 g of crystal salt, you need to convert the mass to moles using the molar mass of NaCl. The molar mass of NaCl is approximately 58.44 g/mol. Divide the mass of the crystal salt by the molar mass of NaCl to find the moles of NaCl, then use Avogadro's number (6.022 x 10^23) to convert moles to formula units.
How much force is needed to lift 70kg box with an 2 minutes per seconds acceleration of the box?
momentum is mass x velocity (p=mv), and velocity is distance divided by time (d/t),so p=m(d/t)=(70kg)(400m/50s)=560 kgm/s================================Answer #2:If the questioner actually knew what he was talking about when he postedthe question, then the runner's average momentum is(70 kg) x (400 miles) x(1,609.344 meters/mile)/(50 seconds) = 9.012 x 105kg-m/secWe can't help but notice that in the question's frame of reference, the runner issteaming along at 28,800 miles per hour. This arouses our curiosity, but is notgermaine to the problem or to its solution, and we play the hand we are dealt.Our math and physics are bullet-proof, and we stand by them.
During an experiment a solution containing 24 mg of phosphorus 32 was preparedHow much of the isotope will remain after 28 days if its half-life is 14 days?
After 28 days, two half-lives would have passed (14 days x 2). This means the initial amount of phosphorus-32 would be reduced by three-quarters (1/2 x 1/2 = 1/4). Therefore, 6 mg (24 mg x 1/4) of phosphorus-32 will remain after 28 days.
What is percentage strength?
I'm not sure if i am correct but you might be referring to relative strength which is strength relative to your body weight. Have you ever been to the gym and seen those big bulky guys lifting heavy weights then the scrawny guy no one pays much attention to comes along and matches or increases the weight the bulky guys were doing. This is relative strength. The ability to lift high weight without resulting in hypertrophy (increased muscle mass). Eg: Mr X weighs 70kg and can bench 70kg, Mr Y weighs 100 kg and can bench 90kg. Although Mr Y can bench 20kg more than Mr X, Mr Y has a higher percentage of relative strength. Mr X has %100 relative strength whereas Mr Y only has %90 relative strength. The main factor in gaining relative strength is diet (mainly protein intake). The bulky guys gain weight because they have an excessive intake of protein, resulting in hypertrophy. If intake is less or the same as expenditure, no weight can be gained. In my opinion hidden power is more meaningful and humble than power that is expressed in an arrogant manner.
