Question

An space probe built on Earth has a mass of 750 kg. Calculate the weight of the space probe on Earth.

Answer 1

7350N

Step-by-step explanation:

Data

m-750kg

g-9.8

W=mg

=750 x 9.8

=7350N

Answer 2

7357.5N

Step-by-step explanation:

Weight is the force used to pull a mass of object towards the centre of the Earth. The force is 9.81 N/kg.

so, Weight = mass × 9.81

the weight of the space probe should be: 750 × 9.81 = 7357.5 N
