Question

1. Calculate the weight of a 50kg mass on Earth (note g = 9.8N/kg)
2. Calculate the weight of a 200kg mass on Earth

3. On Jupiter the gravity measures 23N/kg. Calculate the mass of a rock which has a weight of 4600N.
4. Calculate the weight that the same rock would have on Earth.

5. A 20N force acts at an angle of 25 degrees to the horizontal. Resolve the force to find it's horizontal and vertical components

Answer 1

Answer:

1. Weight is given by the formula,

W=mg.

On Earth, g=9.8 m/s2 . So, the object's weight on Earth will be:

W=50 kg⋅9.8 m/s2.

=490 N.

2. Calculate this one just as I did above

PLEASE, MARK ME AS BRAINLIEST!

Answer 2

1) weight = (mass × gravity) = 50 × 9.8 N = 490 N

2) weight = (mass × gravity) = 200 × 9.8 N = 1960 N

3) mass = (weight ÷ gravity) = 4600 ÷ 23 kg = 200 kg

4) From question number (3) we get the mass of rock i,e, 200 kg

==> gravity on earth = 9.8 m/s²

==> therefore, weight on earth = (mass × gravity) = 1960 N

5) Sorry, I don't know the answer of this one .
