If a person weighs 818 N on earth and 5320 N on the surface of a nearby planet, what is the acceleration due to gravity on that

alexandr402 [8]

Answer:

$g'=63.74\ m/s^2$

Explanation:

It is given that,

Weight of the person on Earth, W = 818 N

Weight of a person is given by the following formula as :

$W=mg$

g is the acceleration due to gravity on earth

$m=\dfrac{W}{g}$

$m=\dfrac{818\ N}{9.8\ m/s^2}$

m = 83.46 kg

The mass of an object is same everywhere. It does not depend on the location.

Let W' is the weight of the person on the surface of a nearby planet, W' = 5320 N

g' is the acceleration due to gravity on that planet. So,

$g'=\dfrac{W'}{m}$

$g'=\dfrac{5320\ N}{83.46\ kg}$

$g'=63.74\ m/s^2$

So, the acceleration due to gravity on that planet is $63.74\ m/s^2$ . Hence, this is the required solution.

10. John has borrowed his parents car without permission and is driving without a license. He

Natasha2012 [34]

Yes

Explanation:
John is driving at 25 meters per second and he has to drive 500 meters to get to his house.
I divided 500 by 25 to see how long it would take for John to get to his house
- 500/25= 20

Therefore, it will take John 20 seconds to reach his driveway, which is 25 seconds less than how long it will take his parents- so he will get to the driveway before them.
