Question

***PLEASE HELP PLS ***

*Round to 1 decimal place
1. What is the mass (in kg) of a 2714 N ​offensive lineman?

2. What is the magnitude of the weight (in Newtons) of a 34.8 kg dog?

3. A 366 g water bottle sits on top of your desk. What is the magnitude of the Force of Gravity (in Newtons) that the water bottle exerts on the Earth?​

4. A grandpa is doing pull ups with a tiger tied around his ankles. What is the total number of forces acting on the grandpa if he is hanging at rest from the pull up bar and the tiger is not touching the ground.

Answer 1

1. weight = mass (in kg) * g
you're given weight as 2714 N so you can just divide by the gravitational constant g (9.81) to get mass
2. same formula, weight = mass * g, but this time you're given mass so you can simply multiply by g to get weight
3. F = mg, same method as #2, using the mass of the water bottle and g to get F. be sure to convert mass to kg first
4. not 100% sure but I think it's just the gravitational force from the tiger and the gravitational force from Earth (2 forces? not sure how they're counting them)

Answer 2

@dude would you mind checking my work when you get a chance

Answer 3

i am very appreciative of you actually writing it out explaining everything! thank you for that, but it's too late in the night for me to understand any of this right now frankly and i have to get this assignment turned in online in a few minutes. is there anyway you would mind giving me just direct numbers/the final answer?

Answer 4

@Vocaloid ^^^ see message above. i will try to do my best in physics and ask questions directly to my teacher. i have problems with that. i do not know why this is my hardest class it seems.
